Calculate the LCM of 517,641,645,993

Given numbers are 517,641,645,993

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

The LCM of 517,641,645,993 is 70751602515.

Find LCM of 517,641,645,993 with Prime Factorization


3 517, 641, 645, 993
517, 641, 215, 331

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

3 x 517 x 641 x 215 x 331 = 70751602515

Therefore, the lowest common multiple of 517,641,645,993 is 70751602515.

LCM Formula to Find Lowest Common Multiple of 517,641,645,993

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.

517 x 641 x 645 x 993 = 212254807545

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.

517 : 1, 11, 47, 517

641 : 1, 641

645 : 1, 3, 5, 15, 43, 129, 215, 645

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,641,645,993, is 1.

Now, the common factors can be found like this.

517:11x 47

641:641

645:3x 5x 43

993:3x 331

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

3 = 3

Therefore, the value for common factors is 3.

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 = 212254807545/(1x3)

LCM = 212254807545/3

LCM = 70751602515

Thus, we can understand that the LCM of 517,641,645,993 is 70751602515.
