The LCM of 836,799,616,781 is 663956216.

Find LCM of 836,799,616,781 with Prime Factorization


2 836, 799, 616, 781
2 418, 799, 308, 781
11 209, 799, 154, 781
19, 799, 14, 71

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

2 x 2 x 11 x 19 x 799 x 14 x 71 = 663956216

Therefore, the lowest common multiple of 836,799,616,781 is 663956216.

LCM Formula to Find Lowest Common Multiple of 836,799,616,781

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 799 x 616 x 781 = 321354808544

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

799 : 1, 17, 47, 799

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,799,616,781, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

799:17x 47

616:2x 2x 2x 7x 11

781:11x 71

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 321354808544/(1x484)

LCM = 321354808544/484

LCM = 663956216

Thus, we can understand that the LCM of 836,799,616,781 is 663956216.
