Given numbers are 781,520,408,862

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

The LCM of 781,520,408,862 is 8926923720.

Find LCM of 781,520,408,862 with Prime Factorization

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

2 x 2 x 2 x 781 x 65 x 51 x 431 = 8926923720

Therefore, the lowest common multiple of 781,520,408,862 is 8926923720.

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.

781 x 520 x 408 x 862 = 142830779520

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.

781 : 1, 11, 71, 781

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,520,408,862, is 1.

Now, the common factors can be found like this.

781:11x 71

520:2x 2x 2x 5x 13

408:2x 2x 2x 3x 17

862:2x 431

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 2 = 16

Therefore, the value for common factors is 16.

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 = 142830779520/(1x16)

LCM = 142830779520/16

LCM = 8926923720

Thus, we can understand that the LCM of 781,520,408,862 is 8926923720.
