Calculate the LCM of 782,854,671,972

Given numbers are 782,854,671,972

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

The LCM of 782,854,671,972 is 1785104244.

Find LCM of 782,854,671,972 with Prime Factorization


2 782, 854, 671, 972
61 391, 427, 671, 486
391, 7, 11, 486

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

2 x 61 x 391 x 7 x 11 x 486 = 1785104244

Therefore, the lowest common multiple of 782,854,671,972 is 1785104244.

LCM Formula to Find Lowest Common Multiple of 782,854,671,972

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.

782 x 854 x 671 x 972 = 435565435536

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

854 : 1, 2, 7, 14, 61, 122, 427, 854

671 : 1, 11, 61, 671

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,854,671,972, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

854:2x 7x 61

671:11x 61

972:2x 2x 3x 3x 3x 3x 3

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

2x 2x 61 = 244

Therefore, the value for common factors is 244.

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 = 435565435536/(1x244)

LCM = 435565435536/244

LCM = 1785104244

Thus, we can understand that the LCM of 782,854,671,972 is 1785104244.
