Given numbers are 813,478,787,959,620

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

The LCM of 813,478,787,959,620 is 90922941119220.

Find LCM of 813,478,787,959,620 with Prime Factorization

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

2 x 813 x 239 x 787 x 959 x 310 = 90922941119220

Therefore, the lowest common multiple of 813,478,787,959,620 is 90922941119220.

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.

813 x 478 x 787 x 959 x 620 = 181845882238440

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.

813 : 1, 3, 271, 813

478 : 1, 2, 239, 478

787 : 1, 787

959 : 1, 7, 137, 959

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,478,787,959,620, is 1.

Now, the common factors can be found like this.

813:3x 271

478:2x 239

787:787

959:7x 137

620:2x 2x 5x 31

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

2 = 2

Therefore, the value for common factors is 2.

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 = 181845882238440/(1x2)

LCM = 181845882238440/2

LCM = 90922941119220

Thus, we can understand that the LCM of 813,478,787,959,620 is 90922941119220.
