Given numbers are 391,956,816,902

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

The LCM of 391,956,816,902 is 2022983952.

Find LCM of 391,956,816,902 with Prime Factorization

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

2 x 2 x 17 x 23 x 239 x 12 x 451 = 2022983952

Therefore, the lowest common multiple of 391,956,816,902 is 2022983952.

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.

391 x 956 x 816 x 902 = 275125817472

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.

391 : 1, 17, 23, 391

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

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

902 : 1, 2, 11, 22, 41, 82, 451, 902

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,956,816,902, is 1.

Now, the common factors can be found like this.

391:17x 23

956:2x 2x 239

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

902:2x 11x 41

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 17 = 136

Therefore, the value for common factors is 136.

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 = 275125817472/(1x136)

LCM = 275125817472/136

LCM = 2022983952

Thus, we can understand that the LCM of 391,956,816,902 is 2022983952.
