Given numbers are 644,107,267,979

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

The LCM of 644,107,267,979 is 202382796.

Find LCM of 644,107,267,979 with Prime Factorization

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

89 x 644 x 107 x 3 x 11 = 202382796

Therefore, the lowest common multiple of 644,107,267,979 is 202382796.

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.

644 x 107 x 267 x 979 = 18012068844

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

107 : 1, 107

267 : 1, 3, 89, 267

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,107,267,979, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

107:107

267:3x 89

979:11x 89

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

89 = 89

Therefore, the value for common factors is 89.

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 = 18012068844/(1x89)

LCM = 18012068844/89

LCM = 202382796

Thus, we can understand that the LCM of 644,107,267,979 is 202382796.
