Given numbers are 642,702,658,127

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

The LCM of 642,702,658,127 is 3138488262.

Find LCM of 642,702,658,127 with Prime Factorization

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

2 x 3 x 107 x 117 x 329 x 127 = 3138488262

Therefore, the lowest common multiple of 642,702,658,127 is 3138488262.

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.

642 x 702 x 658 x 127 = 37661859144

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

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

127 : 1, 127

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,702,658,127, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

702:2x 3x 3x 3x 13

658:2x 7x 47

127:127

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 37661859144/(1x12)

LCM = 37661859144/12

LCM = 3138488262

Thus, we can understand that the LCM of 642,702,658,127 is 3138488262.
