Express each number in terms of its prime factors.
72 = 2 x 2 x 2 x 3 x 3 = 23 x 32
168 = 2 x 2 x 2 x 3 x 7 = 23 x 3 x 7
The LCM is the product of the highest power of each prime factor.
The highest power of 2 is 23, of 3 is 32, of 7 is 7.
The LCM is therefore 23 x 32 x 7 = 8 x 9 x 7 = 504
The lowest common multiple of 8 and 9 is 72.
The LCM is: 72The lowest common multiple of 8 and 18 is 72
360
It is: 72
The LCM is 792.
The lowest common multiple of 24 and 72 is 72.
The lowest common multiple (LCM) is: 72
The lowest common multiple of 8 and 9 is 72.
Least Common Multiple (LCM) for 72 108 is 216
Multiples of 24: 24, 48, 72, 96, 120, 144, 168, 192, ...Multiples of 56: 56, 112, 168, 224, 280, ...Lowest common multiple: 168
Least Common Multiple (LCM) for 48 72 is 144
2 and 3.* * * * *What???The lowest COMMON multiple is 72It is: 72
The LCM is: 72The lowest common multiple of 8 and 18 is 72
It is infinite but the lowest common multiple is 288
10440 I think you mean lowest common multiple. 145 and 72 do not share any common factors, so the lowest common multiple is simply the product of the two numbers.
216
72 is the answer.
