Calculate the LCM of 631,323,399,964

Given numbers are 631,323,399,964

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

The LCM of 631,323,399,964 is 4125990372.

Find LCM of 631,323,399,964 with Prime Factorization


19 631, 323, 399, 964
631, 17, 21, 964

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

19 x 631 x 17 x 21 x 964 = 4125990372

Therefore, the lowest common multiple of 631,323,399,964 is 4125990372.

LCM Formula to Find Lowest Common Multiple of 631,323,399,964

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.

631 x 323 x 399 x 964 = 78393817068

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.

631 : 1, 631

323 : 1, 17, 19, 323

399 : 1, 3, 7, 19, 21, 57, 133, 399

964 : 1, 2, 4, 241, 482, 964

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,323,399,964, is 1.

Now, the common factors can be found like this.

631:631

323:17x 19

399:3x 7x 19

964:2x 2x 241

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

19 = 19

Therefore, the value for common factors is 19.

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 = 78393817068/(1x19)

LCM = 78393817068/19

LCM = 4125990372

Thus, we can understand that the LCM of 631,323,399,964 is 4125990372.
