Least common multiple and greatest common divisor of decimals and fractions 9.6 how to find the least common multiple of 16 18? The simpler the better

Least common multiple and greatest common divisor of decimals and fractions 9.6 how to find the least common multiple of 16 18? The simpler the better

Least common multiple: 3 * 2 * 3 * 1 * 1 * 8 * 1 = 144
Greatest common divisor: 3 * 2 * 3 = 18

The relationship between the greatest common divisor and the least common multiple
All right, reward!

The greatest common divisor is the divisor of the least common multiple
And: the quotient of the least common multiple and the greatest common divisor is equal to the product of the quotient of the two numbers and the greatest common divisor
That is, if the greatest common divisor of X and Y is a and the least common multiple is B, then B / a = (x / a) (Y / a)

The relationship between the greatest common divisor and the least common multiple
How to use the greatest common divisor to find the least common multiple?

Let two numbers be a, B, the greatest common divisor P and the least common multiple Q
So there is a relationship: ab = PQ
So q = AB / P

Find the greatest common divisor and the least common multiple of 10, 34 and 68

10 = 2 × 5, 34 = 2 × 17, 68 = 2 × 2 × 17, so the greatest common divisor of 10, 34 and 68 is 2; the least common multiple is 2 × 17 × 5 × 2 = 340

15. What is the least common multiple of 12 and 10
fast

60

Least common multiple of 10.12.15
It's going to be today. There's a problem in the homework

60
Their least common multiple is 60
60/15=4
60/12=5
60/10=6
Hope to adopt
thank you

Least common multiple of 12, 15, 12 and 15

12 * 15 = 180 at the same time, if you subtract 3 (that is, divide by 3), then 4.5.60 can't be reduced, so the least common multiple is 60

3 times 4 times 13 times 5 = 780

The greatest common divisor of two natural numbers is 7, and the least common multiple is 21. These two numbers are () ()

7 and 21

The greatest common divisor of two numbers is 21, and the least common multiple is 252. What is the minimum sum of these two numbers?

The greatest common divisor of two numbers is 21, and the least common multiple is 252
252=21*2*2*3=21*4*3
3 and 4 are coprime, so one number is 21 * 4 = 84, and the other number is 21 * 3 = 63
