Calculate the LCM of 668,952,824,621

Given numbers are 668,952,824,621

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

The LCM of 668,952,824,621 is 10169093592.

Find LCM of 668,952,824,621 with Prime Factorization


2 668, 952, 824, 621
2 334, 476, 412, 621
2 167, 238, 206, 621
167, 119, 103, 621

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

2 x 2 x 2 x 167 x 119 x 103 x 621 = 10169093592

Therefore, the lowest common multiple of 668,952,824,621 is 10169093592.

LCM Formula to Find Lowest Common Multiple of 668,952,824,621

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 952 x 824 x 621 = 325410994944

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

952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952

824 : 1, 2, 4, 8, 103, 206, 412, 824

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,952,824,621, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

952:2x 2x 2x 7x 17

824:2x 2x 2x 103

621:3x 3x 3x 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 2x 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 325410994944/(1x32)

LCM = 325410994944/32

LCM = 10169093592

Thus, we can understand that the LCM of 668,952,824,621 is 10169093592.
