Given numbers are 130,121,221,668

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

The LCM of 130,121,221,668 is 89314940.

Find LCM of 130,121,221,668 with Prime Factorization

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

2 x 13 x 5 x 121 x 17 x 334 = 89314940

Therefore, the lowest common multiple of 130,121,221,668 is 89314940.

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.

130 x 121 x 221 x 668 = 2322188440

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

121 : 1, 11, 121

221 : 1, 13, 17, 221

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,121,221,668, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

121:11x 11

221:13x 17

668:2x 2x 167

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 2322188440/(1x26)

LCM = 2322188440/26

LCM = 89314940

Thus, we can understand that the LCM of 130,121,221,668 is 89314940.
