35 5X7 = 35
The Least Common Multiple (LCM) for 3 5 7 8 is 840.
40
30
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR and a LOWEST common multiple:gcf(5, 6) = 1lcm(5, 6) = 30
The first one is 5x1=5 the next is 5x2=10 The number itself is always the first multiple. This is important because when finding a common multiple, one needs to consider the number itself as a multiple Example: Find the least common multiple of 5 and 10, the answer is 10 since it is a multiple of itself and 5xs2 is 10.
70
the answer is 70!!
70, 140, 210, etc.
The first common multiple of 5 and 8 is 40 (5x8=40; 8x5=40).
The first common multiple of 3 4 5 and 7 is 420.
