Calculate the LCM of 931,604,425,690,989

Given numbers are 931,604,425,690,989

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

The LCM of 931,604,425,690,989 is 709076505900.

Find LCM of 931,604,425,690,989 with Prime Factorization


2 931, 604, 425, 690, 989
5 931, 302, 425, 345, 989
23 931, 302, 85, 69, 989
931, 302, 85, 3, 43

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

2 x 5 x 23 x 931 x 302 x 85 x 3 x 43 = 709076505900

Therefore, the lowest common multiple of 931,604,425,690,989 is 709076505900.

LCM Formula to Find Lowest Common Multiple of 931,604,425,690,989

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.

931 x 604 x 425 x 690 x 989 = 163087596357000

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.

931 : 1, 7, 19, 49, 133, 931

604 : 1, 2, 4, 151, 302, 604

425 : 1, 5, 17, 25, 85, 425

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,604,425,690,989, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

604:2x 2x 151

425:5x 5x 17

690:2x 3x 5x 23

989:23x 43

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 163087596357000/(1x230)

LCM = 163087596357000/230

LCM = 709076505900

Thus, we can understand that the LCM of 931,604,425,690,989 is 709076505900.
