Given numbers are 756,357,658,861,915

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

The LCM of 756,357,658,861,915 is 7553570220.

Find LCM of 756,357,658,861,915 with Prime Factorization

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

2 x 3 x 7 x 18 x 17 x 47 x 41 x 305 = 7553570220

Therefore, the lowest common multiple of 756,357,658,861,915 is 7553570220.

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.

756 x 357 x 658 x 861 x 915 = 139907227614840

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.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

357 : 1, 3, 7, 17, 21, 51, 119, 357

658 : 1, 2, 7, 14, 47, 94, 329, 658

861 : 1, 3, 7, 21, 41, 123, 287, 861

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,357,658,861,915, is 1.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

357:3x 7x 17

658:2x 7x 47

861:3x 7x 41

915:3x 5x 61

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

2x 3x 3x 3x 7x 7x 7 = 18522

Therefore, the value for common factors is 18522.

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 = 139907227614840/(1x18522)

LCM = 139907227614840/18522

LCM = 7553570220

Thus, we can understand that the LCM of 756,357,658,861,915 is 7553570220.
