Given numbers are 642,478,226,749,152

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

The LCM of 642,478,226,749,152 is 9224078808.

Find LCM of 642,478,226,749,152 with Prime Factorization

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

2 x 107 x 3 x 239 x 113 x 7 x 76 = 9224078808

Therefore, the lowest common multiple of 642,478,226,749,152 is 9224078808.

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 478 x 226 x 749 x 152 = 7895811459648

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

478 : 1, 2, 239, 478

226 : 1, 2, 113, 226

749 : 1, 7, 107, 749

152 : 1, 2, 4, 8, 19, 38, 76, 152

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,478,226,749,152, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

478:2x 239

226:2x 113

749:7x 107

152:2x 2x 2x 19

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 2x 107 = 856

Therefore, the value for common factors is 856.

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 = 7895811459648/(1x856)

LCM = 7895811459648/856

LCM = 9224078808

Thus, we can understand that the LCM of 642,478,226,749,152 is 9224078808.
