Given numbers are 642,438,826,177,912

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

The LCM of 642,438,826,177,912 is 2942060016.

Find LCM of 642,438,826,177,912 with Prime Factorization

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

2 x 3 x 59 x 107 x 73 x 7 x 1 x 152 = 2942060016

Therefore, the lowest common multiple of 642,438,826,177,912 is 2942060016.

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 438 x 826 x 177 x 912 = 37493612843904

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

438 : 1, 2, 3, 6, 73, 146, 219, 438

826 : 1, 2, 7, 14, 59, 118, 413, 826

177 : 1, 3, 59, 177

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,438,826,177,912, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

438:2x 3x 73

826:2x 7x 59

177:3x 59

912:2x 2x 2x 2x 3x 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 3x 3x 3x 59 = 12744

Therefore, the value for common factors is 12744.

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 = 37493612843904/(1x12744)

LCM = 37493612843904/12744

LCM = 2942060016

Thus, we can understand that the LCM of 642,438,826,177,912 is 2942060016.
