Calculate the LCM of 875,645,780,916

Given numbers are 875,645,780,916

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

The LCM of 875,645,780,916 is 1344115500.

Find LCM of 875,645,780,916 with Prime Factorization


2 875, 645, 780, 916
2 875, 645, 390, 458
3 875, 645, 195, 229
5 875, 215, 65, 229
175, 43, 13, 229

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

2 x 2 x 3 x 5 x 175 x 43 x 13 x 229 = 1344115500

Therefore, the lowest common multiple of 875,645,780,916 is 1344115500.

LCM Formula to Find Lowest Common Multiple of 875,645,780,916

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.

875 x 645 x 780 x 916 = 403234650000

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.

875 : 1, 5, 7, 25, 35, 125, 175, 875

645 : 1, 3, 5, 15, 43, 129, 215, 645

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

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,645,780,916, is 1.

Now, the common factors can be found like this.

875:5x 5x 5x 7

645:3x 5x 43

780:2x 2x 3x 5x 13

916:2x 2x 229

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 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 403234650000/(1x300)

LCM = 403234650000/300

LCM = 1344115500

Thus, we can understand that the LCM of 875,645,780,916 is 1344115500.
