Given numbers are 979,208,104,421

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

The LCM of 979,208,104,421 is 85729072.

Find LCM of 979,208,104,421 with Prime Factorization

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

2 x 2 x 2 x 13 x 979 x 1 x 2 x 421 = 85729072

Therefore, the lowest common multiple of 979,208,104,421 is 85729072.

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.

979 x 208 x 104 x 421 = 8915823488

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.

979 : 1, 11, 89, 979

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

104 : 1, 2, 4, 8, 13, 26, 52, 104

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,208,104,421, is 1.

Now, the common factors can be found like this.

979:11x 89

208:2x 2x 2x 2x 13

104:2x 2x 2x 13

421:421

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 13 = 104

Therefore, the value for common factors is 104.

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 = 8915823488/(1x104)

LCM = 8915823488/104

LCM = 85729072

Thus, we can understand that the LCM of 979,208,104,421 is 85729072.
