Given numbers are 392,355,911,639

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

The LCM of 392,355,911,639 is 1140972840.

Find LCM of 392,355,911,639 with Prime Factorization

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

71 x 392 x 5 x 911 x 9 = 1140972840

Therefore, the lowest common multiple of 392,355,911,639 is 1140972840.

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.

392 x 355 x 911 x 639 = 81009071640

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

355 : 1, 5, 71, 355

911 : 1, 911

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,355,911,639, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

355:5x 71

911:911

639:3x 3x 71

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

71 = 71

Therefore, the value for common factors is 71.

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 = 81009071640/(1x71)

LCM = 81009071640/71

LCM = 1140972840

Thus, we can understand that the LCM of 392,355,911,639 is 1140972840.
