Given numbers are 542,428,172,851

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

The LCM of 542,428,172,851 is 4244348884.

Find LCM of 542,428,172,851 with Prime Factorization

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

2 x 2 x 271 x 107 x 43 x 851 = 4244348884

Therefore, the lowest common multiple of 542,428,172,851 is 4244348884.

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.

542 x 428 x 172 x 851 = 33954791072

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.

542 : 1, 2, 271, 542

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

172 : 1, 2, 4, 43, 86, 172

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,428,172,851, is 1.

Now, the common factors can be found like this.

542:2x 271

428:2x 2x 107

172:2x 2x 43

851:23x 37

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 = 33954791072/(1x8)

LCM = 33954791072/8

LCM = 4244348884

Thus, we can understand that the LCM of 542,428,172,851 is 4244348884.
