Given numbers are 648,667,428,169

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

The LCM of 648,667,428,169 is 7815761928.

Find LCM of 648,667,428,169 with Prime Factorization

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

2 x 2 x 162 x 667 x 107 x 169 = 7815761928

Therefore, the lowest common multiple of 648,667,428,169 is 7815761928.

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.

648 x 667 x 428 x 169 = 31263047712

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

667 : 1, 23, 29, 667

428 : 1, 2, 4, 107, 214, 428

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,667,428,169, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

667:23x 29

428:2x 2x 107

169:13x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 31263047712/(1x4)

LCM = 31263047712/4

LCM = 7815761928

Thus, we can understand that the LCM of 648,667,428,169 is 7815761928.
