Calculate the LCM of 836,821,638,617

Given numbers are 836,821,638,617

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

The LCM of 836,821,638,617 is 12280967908.

Find LCM of 836,821,638,617 with Prime Factorization


2 836, 821, 638, 617
11 418, 821, 319, 617
38, 821, 29, 617

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

2 x 11 x 38 x 821 x 29 x 617 = 12280967908

Therefore, the lowest common multiple of 836,821,638,617 is 12280967908.

LCM Formula to Find Lowest Common Multiple of 836,821,638,617

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.

836 x 821 x 638 x 617 = 270181293976

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.

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

821 : 1, 821

638 : 1, 2, 11, 22, 29, 58, 319, 638

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,821,638,617, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

821:821

638:2x 11x 29

617:617

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 270181293976/(1x22)

LCM = 270181293976/22

LCM = 12280967908

Thus, we can understand that the LCM of 836,821,638,617 is 12280967908.
