Given numbers are 647,473,121,506

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

The LCM of 647,473,121,506 is 154851686.

Find LCM of 647,473,121,506 with Prime Factorization

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

11 x 647 x 43 x 11 x 46 = 154851686

Therefore, the lowest common multiple of 647,473,121,506 is 154851686.

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.

647 x 473 x 121 x 506 = 18737054006

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.

647 : 1, 647

473 : 1, 11, 43, 473

121 : 1, 11, 121

506 : 1, 2, 11, 22, 23, 46, 253, 506

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,473,121,506, is 1.

Now, the common factors can be found like this.

647:647

473:11x 43

121:11x 11

506:2x 11x 23

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 18737054006/(1x121)

LCM = 18737054006/121

LCM = 154851686

Thus, we can understand that the LCM of 647,473,121,506 is 154851686.
