The greatest common factor and the least common multiple of 14 and 38, 42 and 90 are

The greatest common factor and the least common multiple of 14 and 38, 42 and 90 are

The greatest common factor of 14 and 38 is 2, and the least common multiple is 266
The greatest common factor of 42 and 90 is 6, and the least common multiple is 630

The least common multiple of 14 and 8

56. Let me explain to you, children, using the product of 2x7 = 14, using the product of 2x4 = 8.14 and the common factor of 8 is 2, so there is no need to multiply. So the final answer = 2x7x4 = 56! You must study hard!

The least common multiple of 14 and 21
This is my homework. I really can't do it
What is the least common multiple of 6 and 8

42,2
The way to find the common multiple: first, find out the common factor of these two numbers, which is 7. Remember it, 14 in addition to seven, there are still 2, 21 divided by 7, quotient 3. Multiply these three numbers to get 7 times 2 times 3
Greatest common factor: first find out their factors, 6 has 1,2,3,6,
The factor of 8 is 1,2,4,8, and then find out the biggest one, which is 2
The concept needs to be understood

The least common multiple of 14 and 70

14 = 2 × 7 70 = 2 × 5 × 7
2 and 7 are repeated, using 2 × 7 × 5 = 70. There is another way, they are in multiple relation, and the least common multiple is the larger number, which is 70
