Calculate the LCM of 671,671,620

Given numbers are 671,671,620

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

The LCM of 671,671,620 is 416020.

Find LCM of 671,671,620 with Prime Factorization


11 671, 671, 620
61 61, 61, 620
1, 1, 620

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

11 x 61 x 1 x 1 x 620 = 416020

Therefore, the lowest common multiple of 671,671,620 is 416020.

LCM Formula to Find Lowest Common Multiple of 671,671,620

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.

671 x 671 x 620 = 279149420

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.

671 : 1, 11, 61, 671

671 : 1, 11, 61, 671

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,671,620, is 1.

Now, the common factors can be found like this.

671:11x 61

671:11x 61

620:2x 2x 5x 31

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

11x 61 = 671

Therefore, the value for common factors is 671.

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 = 279149420/(1x671)

LCM = 279149420/671

LCM = 416020

Thus, we can understand that the LCM of 671,671,620 is 416020.
