Calculate the LCM of 667,633,422,690

Given numbers are 667,633,422,690

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

The LCM of 667,633,422,690 is 4222110.

Find LCM of 667,633,422,690 with Prime Factorization


2 667, 633, 422, 690
3 667, 633, 211, 345
23 667, 211, 211, 115
211 29, 211, 211, 5
29, 1, 1, 5

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

2 x 3 x 23 x 211 x 29 x 1 x 1 x 5 = 4222110

Therefore, the lowest common multiple of 667,633,422,690 is 4222110.

LCM Formula to Find Lowest Common Multiple of 667,633,422,690

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.

667 x 633 x 422 x 690 = 122939398980

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.

667 : 1, 23, 29, 667

633 : 1, 3, 211, 633

422 : 1, 2, 211, 422

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,633,422,690, is 1.

Now, the common factors can be found like this.

667:23x 29

633:3x 211

422:2x 211

690:2x 3x 5x 23

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

2x 3x 23x 211 = 29118

Therefore, the value for common factors is 29118.

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 = 122939398980/(1x29118)

LCM = 122939398980/29118

LCM = 4222110

Thus, we can understand that the LCM of 667,633,422,690 is 4222110.
