Given numbers are 781,442,816,130,956

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

The LCM of 781,442,816,130,956 is 9900393360.

Find LCM of 781,442,816,130,956 with Prime Factorization

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

2 x 2 x 13 x 17 x 781 x 1 x 12 x 5 x 239 = 9900393360

Therefore, the lowest common multiple of 781,442,816,130,956 is 9900393360.

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 442 x 816 x 130 x 956 = 35007790920960

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

130 : 1, 2, 5, 10, 13, 26, 65, 130

956 : 1, 2, 4, 239, 478, 956

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,442,816,130,956, is 1.

Now, the common factors can be found like this.

781:11x 71

442:2x 13x 17

816:2x 2x 2x 2x 3x 17

130:2x 5x 13

956:2x 2x 239

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 2x 13x 17 = 3536

Therefore, the value for common factors is 3536.

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 = 35007790920960/(1x3536)

LCM = 35007790920960/3536

LCM = 9900393360

Thus, we can understand that the LCM of 781,442,816,130,956 is 9900393360.
