The LCM of 813,429,749,920 is 80111751720.

Find LCM of 813,429,749,920 with Prime Factorization


3 813, 429, 749, 920
271, 143, 749, 920

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

3 x 271 x 143 x 749 x 920 = 80111751720

Therefore, the lowest common multiple of 813,429,749,920 is 80111751720.

LCM Formula to Find Lowest Common Multiple of 813,429,749,920

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.

813 x 429 x 749 x 920 = 240335255160

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.

813 : 1, 3, 271, 813

429 : 1, 3, 11, 13, 33, 39, 143, 429

749 : 1, 7, 107, 749

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,429,749,920, is 1.

Now, the common factors can be found like this.

813:3x 271

429:3x 11x 13

749:7x 107

920:2x 2x 2x 5x 23

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 = 240335255160/(1x3)

LCM = 240335255160/3

LCM = 80111751720

Thus, we can understand that the LCM of 813,429,749,920 is 80111751720.
