Given numbers are 219,951,657,421

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

The LCM of 219,951,657,421 is 87681249.

Find LCM of 219,951,657,421 with Prime Factorization

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

3 x 73 x 1 x 317 x 3 x 421 = 87681249

Therefore, the lowest common multiple of 219,951,657,421 is 87681249.

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.

219 x 951 x 657 x 421 = 57606580593

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.

219 : 1, 3, 73, 219

951 : 1, 3, 317, 951

657 : 1, 3, 9, 73, 219, 657

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,951,657,421, is 1.

Now, the common factors can be found like this.

219:3x 73

951:3x 317

657:3x 3x 73

421:421

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

3x 3x 73 = 657

Therefore, the value for common factors is 657.

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 = 57606580593/(1x657)

LCM = 57606580593/657

LCM = 87681249

Thus, we can understand that the LCM of 219,951,657,421 is 87681249.
