Given numbers are 979,842,421

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

The LCM of 979,842,421 is 824318.

Find LCM of 979,842,421 with Prime Factorization

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

421 x 979 x 2 x 1 = 824318

Therefore, the lowest common multiple of 979,842,421 is 824318.

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 842 x 421 = 347037878

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

842 : 1, 2, 421, 842

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,842,421, is 1.

Now, the common factors can be found like this.

979:11x 89

842:2x 421

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.

421 = 421

Therefore, the value for common factors is 421.

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 = 347037878/(1x421)

LCM = 347037878/421

LCM = 824318

Thus, we can understand that the LCM of 979,842,421 is 824318.

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

• LCM of 753, 181, 824
