Calculate the LCM of 641,325,636,626

Given numbers are 641,325,636,626

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

The LCM of 641,325,636,626 is 41470841100.

Find LCM of 641,325,636,626 with Prime Factorization


2 641, 325, 636, 626
641, 325, 318, 313

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

2 x 641 x 325 x 318 x 313 = 41470841100

Therefore, the lowest common multiple of 641,325,636,626 is 41470841100.

LCM Formula to Find Lowest Common Multiple of 641,325,636,626

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.

641 x 325 x 636 x 626 = 82941682200

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.

641 : 1, 641

325 : 1, 5, 13, 25, 65, 325

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,325,636,626, is 1.

Now, the common factors can be found like this.

641:641

325:5x 5x 13

636:2x 2x 3x 53

626:2x 313

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 = 82941682200/(1x2)

LCM = 82941682200/2

LCM = 41470841100

Thus, we can understand that the LCM of 641,325,636,626 is 41470841100.
