Given numbers are 551,721,194,392

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

The LCM of 551,721,194,392 is 2157976072.

Find LCM of 551,721,194,392 with Prime Factorization

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

2 x 7 x 551 x 103 x 97 x 28 = 2157976072

Therefore, the lowest common multiple of 551,721,194,392 is 2157976072.

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.

551 x 721 x 194 x 392 = 30211665008

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.

551 : 1, 19, 29, 551

721 : 1, 7, 103, 721

194 : 1, 2, 97, 194

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,721,194,392, is 1.

Now, the common factors can be found like this.

551:19x 29

721:7x 103

194:2x 97

392:2x 2x 2x 7x 7

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 30211665008/(1x14)

LCM = 30211665008/14

LCM = 2157976072

Thus, we can understand that the LCM of 551,721,194,392 is 2157976072.
