Given numbers are 221,937,506,642,478

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

The LCM of 221,937,506,642,478 is 8038690623678.

Find LCM of 221,937,506,642,478 with Prime Factorization

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

2 x 221 x 937 x 253 x 321 x 239 = 8038690623678

Therefore, the lowest common multiple of 221,937,506,642,478 is 8038690623678.

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 937 x 506 x 642 x 478 = 32154762494712

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

937 : 1, 937

506 : 1, 2, 11, 22, 23, 46, 253, 506

642 : 1, 2, 3, 6, 107, 214, 321, 642

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,937,506,642,478, is 1.

Now, the common factors can be found like this.

221:13x 17

937:937

506:2x 11x 23

642:2x 3x 107

478:2x 239

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 32154762494712/(1x4)

LCM = 32154762494712/4

LCM = 8038690623678

Thus, we can understand that the LCM of 221,937,506,642,478 is 8038690623678.
