Given numbers are 657,689,520

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

The LCM of 657,689,520 is 18106920.

Find LCM of 657,689,520 with Prime Factorization

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

13 x 657 x 53 x 40 = 18106920

Therefore, the lowest common multiple of 657,689,520 is 18106920.

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.

657 x 689 x 520 = 235389960

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.

657 : 1, 3, 9, 73, 219, 657

689 : 1, 13, 53, 689

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,689,520, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

689:13x 53

520:2x 2x 2x 5x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 235389960/(1x13)

LCM = 235389960/13

LCM = 18106920

Thus, we can understand that the LCM of 657,689,520 is 18106920.
