Calculate the LCM of 671,914,984,780

Given numbers are 671,914,984,780

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

The LCM of 671,914,984,780 is 19613142120.

Find LCM of 671,914,984,780 with Prime Factorization


2 671, 914, 984, 780
2 671, 457, 492, 390
3 671, 457, 246, 195
671, 457, 82, 65

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

2 x 2 x 3 x 671 x 457 x 82 x 65 = 19613142120

Therefore, the lowest common multiple of 671,914,984,780 is 19613142120.

LCM Formula to Find Lowest Common Multiple of 671,914,984,780

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 914 x 984 x 780 = 470715410880

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

914 : 1, 2, 457, 914

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,914,984,780, is 1.

Now, the common factors can be found like this.

671:11x 61

914:2x 457

984:2x 2x 2x 3x 41

780:2x 2x 3x 5x 13

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 470715410880/(1x24)

LCM = 470715410880/24

LCM = 19613142120

Thus, we can understand that the LCM of 671,914,984,780 is 19613142120.
