Given numbers are 718,702,172

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 718,702,172 is 21673548.

Find LCM of 718,702,172 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 359 x 351 x 86 = 21673548

Therefore, the lowest common multiple of 718,702,172 is 21673548.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

718 x 702 x 172 = 86694192

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

718 : 1, 2, 359, 718

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

172 : 1, 2, 4, 43, 86, 172

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,702,172, is 2.

Now, the common factors can be found like this.

718:2x 359

702:2x 3x 3x 3x 13

172:2x 2x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 86694192/(2x2)

LCM = 86694192/4

LCM = 21673548

Thus, we can understand that the LCM of 718,702,172 is 21673548.
