The LCM of 286,868,520,767 is 73233160.

Find LCM of 286,868,520,767 with Prime Factorization


2 286, 868, 520, 767
2 143, 434, 260, 767
13 143, 217, 130, 767
11, 217, 10, 59

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

2 x 2 x 13 x 11 x 217 x 10 x 59 = 73233160

Therefore, the lowest common multiple of 286,868,520,767 is 73233160.

LCM Formula to Find Lowest Common Multiple of 286,868,520,767

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.

286 x 868 x 520 x 767 = 99011232320

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

767 : 1, 13, 59, 767

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,868,520,767, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

868:2x 2x 7x 31

520:2x 2x 2x 5x 13

767:13x 59

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 2x 13x 13 = 1352

Therefore, the value for common factors is 1352.

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 = 99011232320/(1x1352)

LCM = 99011232320/1352

LCM = 73233160

Thus, we can understand that the LCM of 286,868,520,767 is 73233160.
