Calculate the LCM of 393,988,856,757

Given numbers are 393,988,856,757

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

The LCM of 393,988,856,757 is 62901231432.

Find LCM of 393,988,856,757 with Prime Factorization


2 393, 988, 856, 757
2 393, 494, 428, 757
393, 247, 214, 757

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

2 x 2 x 393 x 247 x 214 x 757 = 62901231432

Therefore, the lowest common multiple of 393,988,856,757 is 62901231432.

LCM Formula to Find Lowest Common Multiple of 393,988,856,757

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.

393 x 988 x 856 x 757 = 251604925728

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.

393 : 1, 3, 131, 393

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

856 : 1, 2, 4, 8, 107, 214, 428, 856

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,988,856,757, is 1.

Now, the common factors can be found like this.

393:3x 131

988:2x 2x 13x 19

856:2x 2x 2x 107

757:757

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 251604925728/(1x4)

LCM = 251604925728/4

LCM = 62901231432

Thus, we can understand that the LCM of 393,988,856,757 is 62901231432.
