Given numbers are 991,230,422,102

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

The LCM of 991,230,422,102 is 2452754730.

Find LCM of 991,230,422,102 with Prime Factorization

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

2 x 991 x 115 x 211 x 51 = 2452754730

Therefore, the lowest common multiple of 991,230,422,102 is 2452754730.

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.

991 x 230 x 422 x 102 = 9811018920

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.

991 : 1, 991

230 : 1, 2, 5, 10, 23, 46, 115, 230

422 : 1, 2, 211, 422

102 : 1, 2, 3, 6, 17, 34, 51, 102

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,230,422,102, is 1.

Now, the common factors can be found like this.

991:991

230:2x 5x 23

422:2x 211

102:2x 3x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 9811018920/(1x4)

LCM = 9811018920/4

LCM = 2452754730

Thus, we can understand that the LCM of 991,230,422,102 is 2452754730.
