Calculate the LCM of 639,358,726,975

Given numbers are 639,358,726,975

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

The LCM of 639,358,726,975 is 8996065650.

Find LCM of 639,358,726,975 with Prime Factorization


2 639, 358, 726, 975
3 639, 179, 363, 975
213, 179, 121, 325

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

2 x 3 x 213 x 179 x 121 x 325 = 8996065650

Therefore, the lowest common multiple of 639,358,726,975 is 8996065650.

LCM Formula to Find Lowest Common Multiple of 639,358,726,975

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.

639 x 358 x 726 x 975 = 161929181700

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.

639 : 1, 3, 9, 71, 213, 639

358 : 1, 2, 179, 358

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,358,726,975, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

358:2x 179

726:2x 3x 11x 11

975:3x 5x 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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 161929181700/(1x18)

LCM = 161929181700/18

LCM = 8996065650

Thus, we can understand that the LCM of 639,358,726,975 is 8996065650.
