Given numbers are 671,649,121,916

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

The LCM of 671,649,121,916 is 398898764.

Find LCM of 671,649,121,916 with Prime Factorization

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

11 x 61 x 59 x 11 x 916 = 398898764

Therefore, the lowest common multiple of 671,649,121,916 is 398898764.

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 649 x 121 x 916 = 48266750444

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

649 : 1, 11, 59, 649

121 : 1, 11, 121

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,649,121,916, is 1.

Now, the common factors can be found like this.

671:11x 61

649:11x 59

121:11x 11

916:2x 2x 229

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 = 48266750444/(1x121)

LCM = 48266750444/121

LCM = 398898764

Thus, we can understand that the LCM of 671,649,121,916 is 398898764.
