The LCM of 681,780,418,494 is 37005540.

Find LCM of 681,780,418,494 with Prime Factorization


2 681, 780, 418, 494
3 681, 390, 209, 247
13 227, 130, 209, 247
19 227, 10, 209, 19
227, 10, 11, 1

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

2 x 3 x 13 x 19 x 227 x 10 x 11 x 1 = 37005540

Therefore, the lowest common multiple of 681,780,418,494 is 37005540.

LCM Formula to Find Lowest Common Multiple of 681,780,418,494

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.

681 x 780 x 418 x 494 = 109684420560

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.

681 : 1, 3, 227, 681

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

418 : 1, 2, 11, 19, 22, 38, 209, 418

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,780,418,494, is 1.

Now, the common factors can be found like this.

681:3x 227

780:2x 2x 3x 5x 13

418:2x 11x 19

494:2x 13x 19

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 3x 13x 19 = 2964

Therefore, the value for common factors is 2964.

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 = 109684420560/(1x2964)

LCM = 109684420560/2964

LCM = 37005540

Thus, we can understand that the LCM of 681,780,418,494 is 37005540.
