The least common multiple of 5, 10 and 12 ()

The least common multiple of 5, 10 and 12 ()

sixty

Is 12 the least common multiple or the common factor of 3 and 4

Least common multiple, multiple, multiple. It's multiple, 3x4 = 12

If a △ B = 12, then the greatest common divisor of a and B is______ The least common multiple of a and 12 is______ ．

Because a △ B = 12, the greatest common divisor of a and B is B, because a △ B = 12, so a △ 12 = B, so the least common multiple of a and 12 is a, so the answer is: B, a

Two thirds of a number is 36 less than three fourths of a number?
Write the quantitative relationship

Let this number be X
Three quarters X - two thirds x = 36
9x out of 12 - 8x out of 12 = 36
12 / 12 x = 36
X=432
