Given numbers are 671,891,722,991

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

The LCM of 671,891,722,991 is 38888249202.

Find LCM of 671,891,722,991 with Prime Factorization

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

11 x 61 x 81 x 722 x 991 = 38888249202

Therefore, the lowest common multiple of 671,891,722,991 is 38888249202.

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 891 x 722 x 991 = 427770741222

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

722 : 1, 2, 19, 38, 361, 722

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,891,722,991, is 1.

Now, the common factors can be found like this.

671:11x 61

891:3x 3x 3x 3x 11

722:2x 19x 19

991:991

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

11 = 11

Therefore, the value for common factors is 11.

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 = 427770741222/(1x11)

LCM = 427770741222/11

LCM = 38888249202

Thus, we can understand that the LCM of 671,891,722,991 is 38888249202.
