Calculate the LCM of 887,671,861,357,778

Given numbers are 887,671,861,357,778

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

The LCM of 887,671,861,357,778 is 6777629272722.

Find LCM of 887,671,861,357,778 with Prime Factorization


3 887, 671, 861, 357, 778
7 887, 671, 287, 119, 778
887, 671, 41, 17, 778

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

3 x 7 x 887 x 671 x 41 x 17 x 778 = 6777629272722

Therefore, the lowest common multiple of 887,671,861,357,778 is 6777629272722.

LCM Formula to Find Lowest Common Multiple of 887,671,861,357,778

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.

887 x 671 x 861 x 357 x 778 = 142330214727162

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.

887 : 1, 887

671 : 1, 11, 61, 671

861 : 1, 3, 7, 21, 41, 123, 287, 861

357 : 1, 3, 7, 17, 21, 51, 119, 357

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,671,861,357,778, is 1.

Now, the common factors can be found like this.

887:887

671:11x 61

861:3x 7x 41

357:3x 7x 17

778:2x 389

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 142330214727162/(1x21)

LCM = 142330214727162/21

LCM = 6777629272722

Thus, we can understand that the LCM of 887,671,861,357,778 is 6777629272722.
