Given numbers are 217,397,651,872

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

The LCM of 217,397,651,872 is 225365784.

Find LCM of 217,397,651,872 with Prime Factorization

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

7 x 31 x 1 x 397 x 3 x 872 = 225365784

Therefore, the lowest common multiple of 217,397,651,872 is 225365784.

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.

217 x 397 x 651 x 872 = 48904375128

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.

217 : 1, 7, 31, 217

397 : 1, 397

651 : 1, 3, 7, 21, 31, 93, 217, 651

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,397,651,872, is 1.

Now, the common factors can be found like this.

217:7x 31

397:397

651:3x 7x 31

872:2x 2x 2x 109

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

7x 31 = 217

Therefore, the value for common factors is 217.

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 = 48904375128/(1x217)

LCM = 48904375128/217

LCM = 225365784

Thus, we can understand that the LCM of 217,397,651,872 is 225365784.
