Given numbers are 672,845,321,715

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

The LCM of 672,845,321,715 is 668347680.

Find LCM of 672,845,321,715 with Prime Factorization

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

3 x 5 x 13 x 224 x 13 x 107 x 11 = 668347680

Therefore, the lowest common multiple of 672,845,321,715 is 668347680.

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.

672 x 845 x 321 x 715 = 130327797600

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

845 : 1, 5, 13, 65, 169, 845

321 : 1, 3, 107, 321

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,845,321,715, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

845:5x 13x 13

321:3x 107

715:5x 11x 13

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

3x 5x 13 = 195

Therefore, the value for common factors is 195.

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 = 130327797600/(1x195)

LCM = 130327797600/195

LCM = 668347680

Thus, we can understand that the LCM of 672,845,321,715 is 668347680.
