Given numbers are 977,991,236,860,891

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

The LCM of 977,991,236,860,891 is 43771999453380.

Find LCM of 977,991,236,860,891 with Prime Factorization

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

2 x 2 x 977 x 991 x 59 x 215 x 891 = 43771999453380

Therefore, the lowest common multiple of 977,991,236,860,891 is 43771999453380.

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.

977 x 991 x 236 x 860 x 891 = 175087997813520

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.

977 : 1, 977

991 : 1, 991

236 : 1, 2, 4, 59, 118, 236

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,991,236,860,891, is 1.

Now, the common factors can be found like this.

977:977

991:991

236:2x 2x 59

860:2x 2x 5x 43

891:3x 3x 3x 3x 11

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 = 175087997813520/(1x4)

LCM = 175087997813520/4

LCM = 43771999453380

Thus, we can understand that the LCM of 977,991,236,860,891 is 43771999453380.
