Calculate the LCM of 668,631,565,921,422

Given numbers are 668,631,565,921,422

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

The LCM of 668,631,565,921,422 is 46280320198620.

Find LCM of 668,631,565,921,422 with Prime Factorization


2 668, 631, 565, 921, 422
334, 631, 565, 921, 211

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

2 x 334 x 631 x 565 x 921 x 211 = 46280320198620

Therefore, the lowest common multiple of 668,631,565,921,422 is 46280320198620.

LCM Formula to Find Lowest Common Multiple of 668,631,565,921,422

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.

668 x 631 x 565 x 921 x 422 = 92560640397240

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.

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

631 : 1, 631

565 : 1, 5, 113, 565

921 : 1, 3, 307, 921

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,631,565,921,422, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

631:631

565:5x 113

921:3x 307

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 92560640397240/(1x2)

LCM = 92560640397240/2

LCM = 46280320198620

Thus, we can understand that the LCM of 668,631,565,921,422 is 46280320198620.
