Calculate the LCM of 639,398,956,948

Given numbers are 639,398,956,948

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

The LCM of 639,398,956,948 is 9603707364.

Find LCM of 639,398,956,948 with Prime Factorization


2 639, 398, 956, 948
2 639, 199, 478, 474
3 639, 199, 239, 237
213, 199, 239, 79

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

2 x 2 x 3 x 213 x 199 x 239 x 79 = 9603707364

Therefore, the lowest common multiple of 639,398,956,948 is 9603707364.

LCM Formula to Find Lowest Common Multiple of 639,398,956,948

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 398 x 956 x 948 = 230488976736

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

398 : 1, 2, 199, 398

956 : 1, 2, 4, 239, 478, 956

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,398,956,948, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

398:2x 199

956:2x 2x 239

948:2x 2x 3x 79

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 230488976736/(1x24)

LCM = 230488976736/24

LCM = 9603707364

Thus, we can understand that the LCM of 639,398,956,948 is 9603707364.
