Calculate the LCM of 310,816,287,779

Given numbers are 310,816,287,779

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

The LCM of 310,816,287,779 is 689695440.

Find LCM of 310,816,287,779 with Prime Factorization


2 310, 816, 287, 779
41 155, 408, 287, 779
155, 408, 7, 19

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

2 x 41 x 155 x 408 x 7 x 19 = 689695440

Therefore, the lowest common multiple of 310,816,287,779 is 689695440.

LCM Formula to Find Lowest Common Multiple of 310,816,287,779

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.

310 x 816 x 287 x 779 = 56555026080

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

287 : 1, 7, 41, 287

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,816,287,779, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

816:2x 2x 2x 2x 3x 17

287:7x 41

779:19x 41

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

2x 41 = 82

Therefore, the value for common factors is 82.

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 = 56555026080/(1x82)

LCM = 56555026080/82

LCM = 689695440

Thus, we can understand that the LCM of 310,816,287,779 is 689695440.
