Given numbers are 971,561,219,219

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

The LCM of 971,561,219,219 is 39765363.

Find LCM of 971,561,219,219 with Prime Factorization

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

3 x 73 x 971 x 187 x 1 x 1 = 39765363

Therefore, the lowest common multiple of 971,561,219,219 is 39765363.

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.

971 x 561 x 219 x 219 = 26125843491

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.

971 : 1, 971

561 : 1, 3, 11, 17, 33, 51, 187, 561

219 : 1, 3, 73, 219

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,561,219,219, is 1.

Now, the common factors can be found like this.

971:971

561:3x 11x 17

219:3x 73

219:3x 73

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 = 26125843491/(1x657)

LCM = 26125843491/657

LCM = 39765363

Thus, we can understand that the LCM of 971,561,219,219 is 39765363.
