Given numbers are 653,638,106,991

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

The LCM of 653,638,106,991 is 21881817122.

Find LCM of 653,638,106,991 with Prime Factorization

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

2 x 653 x 319 x 53 x 991 = 21881817122

Therefore, the lowest common multiple of 653,638,106,991 is 21881817122.

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.

653 x 638 x 106 x 991 = 43763634244

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.

653 : 1, 653

638 : 1, 2, 11, 22, 29, 58, 319, 638

106 : 1, 2, 53, 106

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,638,106,991, is 1.

Now, the common factors can be found like this.

653:653

638:2x 11x 29

106:2x 53

991:991

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 = 43763634244/(1x2)

LCM = 43763634244/2

LCM = 21881817122

Thus, we can understand that the LCM of 653,638,106,991 is 21881817122.

Here are some samples of LCM of two or more Numbers calculations.
