Calculate the LCM of 398,959,730,961

Given numbers are 398,959,730,961

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

The LCM of 398,959,730,961 is 133880686730.

Find LCM of 398,959,730,961 with Prime Factorization


2 398, 959, 730, 961
199, 959, 365, 961

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

2 x 199 x 959 x 365 x 961 = 133880686730

Therefore, the lowest common multiple of 398,959,730,961 is 133880686730.

LCM Formula to Find Lowest Common Multiple of 398,959,730,961

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.

398 x 959 x 730 x 961 = 267761373460

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.

398 : 1, 2, 199, 398

959 : 1, 7, 137, 959

730 : 1, 2, 5, 10, 73, 146, 365, 730

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,959,730,961, is 1.

Now, the common factors can be found like this.

398:2x 199

959:7x 137

730:2x 5x 73

961:31x 31

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

2 = 2

Therefore, the value for common factors is 2.

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 = 267761373460/(1x2)

LCM = 267761373460/2

LCM = 133880686730

Thus, we can understand that the LCM of 398,959,730,961 is 133880686730.
