Calculate the LCM of 938,824,646,708

Given numbers are 938,824,646,708

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

The LCM of 938,824,646,708 is 22094075976.

Find LCM of 938,824,646,708 with Prime Factorization


2 938, 824, 646, 708
2 469, 412, 323, 354
469, 206, 323, 177

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

2 x 2 x 469 x 206 x 323 x 177 = 22094075976

Therefore, the lowest common multiple of 938,824,646,708 is 22094075976.

LCM Formula to Find Lowest Common Multiple of 938,824,646,708

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.

938 x 824 x 646 x 708 = 353505215616

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

824 : 1, 2, 4, 8, 103, 206, 412, 824

646 : 1, 2, 17, 19, 34, 38, 323, 646

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,824,646,708, is 2.

Now, the common factors can be found like this.

938:2x 7x 67

824:2x 2x 2x 103

646:2x 17x 19

708:2x 2x 3x 59

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 2 = 8

Therefore, the value for common factors is 8.

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 = 353505215616/(2x8)

LCM = 353505215616/16

LCM = 22094075976

Thus, we can understand that the LCM of 938,824,646,708 is 22094075976.
