Calculate the LCM of 817,539,715,957

Given numbers are 817,539,715,957

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

The LCM of 817,539,715,957 is 2490252765.

Find LCM of 817,539,715,957 with Prime Factorization


11 817, 539, 715, 957
817, 49, 65, 87

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

11 x 817 x 49 x 65 x 87 = 2490252765

Therefore, the lowest common multiple of 817,539,715,957 is 2490252765.

LCM Formula to Find Lowest Common Multiple of 817,539,715,957

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.

817 x 539 x 715 x 957 = 301320584565

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.

817 : 1, 19, 43, 817

539 : 1, 7, 11, 49, 77, 539

715 : 1, 5, 11, 13, 55, 65, 143, 715

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,539,715,957, is 1.

Now, the common factors can be found like this.

817:19x 43

539:7x 7x 11

715:5x 11x 13

957:3x 11x 29

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 301320584565/(1x121)

LCM = 301320584565/121

LCM = 2490252765

Thus, we can understand that the LCM of 817,539,715,957 is 2490252765.
