Given numbers are 807,638,781,118

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

The LCM of 807,638,781,118 is 2156773674.

Find LCM of 807,638,781,118 with Prime Factorization

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

2 x 11 x 807 x 29 x 71 x 59 = 2156773674

Therefore, the lowest common multiple of 807,638,781,118 is 2156773674.

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.

807 x 638 x 781 x 118 = 47449020828

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.

807 : 1, 3, 269, 807

638 : 1, 2, 11, 22, 29, 58, 319, 638

781 : 1, 11, 71, 781

118 : 1, 2, 59, 118

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,638,781,118, is 1.

Now, the common factors can be found like this.

807:3x 269

638:2x 11x 29

781:11x 71

118:2x 59

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 47449020828/(1x22)

LCM = 47449020828/22

LCM = 2156773674

Thus, we can understand that the LCM of 807,638,781,118 is 2156773674.
