Given numbers are 221,872,318,756

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

The LCM of 221,872,318,756 is 1930396104.

Find LCM of 221,872,318,756 with Prime Factorization

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

2 x 2 x 3 x 221 x 218 x 53 x 63 = 1930396104

Therefore, the lowest common multiple of 221,872,318,756 is 1930396104.

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.

221 x 872 x 318 x 756 = 46329506496

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.

221 : 1, 13, 17, 221

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

318 : 1, 2, 3, 6, 53, 106, 159, 318

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,872,318,756, is 1.

Now, the common factors can be found like this.

221:13x 17

872:2x 2x 2x 109

318:2x 3x 53

756:2x 2x 3x 3x 3x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 46329506496/(1x24)

LCM = 46329506496/24

LCM = 1930396104

Thus, we can understand that the LCM of 221,872,318,756 is 1930396104.
