Calculate the LCM of 660,121,422

Given numbers are 660,121,422

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

The LCM of 660,121,422 is 1531860.

Find LCM of 660,121,422 with Prime Factorization


2 660, 121, 422
11 330, 121, 211
30, 11, 211

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

2 x 11 x 30 x 11 x 211 = 1531860

Therefore, the lowest common multiple of 660,121,422 is 1531860.

LCM Formula to Find Lowest Common Multiple of 660,121,422

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.

660 x 121 x 422 = 33700920

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

121 : 1, 11, 121

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,121,422, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

121:11x 11

422:2x 211

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 33700920/(1x22)

LCM = 33700920/22

LCM = 1531860

Thus, we can understand that the LCM of 660,121,422 is 1531860.
