Calculate the LCM of 641,656,146,626

Given numbers are 641,656,146,626

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

The LCM of 641,656,146,626 is 9607913104.

Find LCM of 641,656,146,626 with Prime Factorization


2 641, 656, 146, 626
641, 328, 73, 313

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

2 x 641 x 328 x 73 x 313 = 9607913104

Therefore, the lowest common multiple of 641,656,146,626 is 9607913104.

LCM Formula to Find Lowest Common Multiple of 641,656,146,626

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 656 x 146 x 626 = 38431652416

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

146 : 1, 2, 73, 146

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,656,146,626, is 1.

Now, the common factors can be found like this.

641:641

656:2x 2x 2x 2x 41

146:2x 73

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 38431652416/(1x4)

LCM = 38431652416/4

LCM = 9607913104

Thus, we can understand that the LCM of 641,656,146,626 is 9607913104.
