Find LCM of 765,548,288,991,494 with Prime Factorization


2 765, 548, 288, 991, 494
2 765, 274, 144, 991, 247
3 765, 137, 72, 991, 247
3 255, 137, 24, 991, 247
85, 137, 8, 991, 247

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

2 x 2 x 3 x 3 x 85 x 137 x 8 x 991 x 247 = 820923311520

Therefore, the lowest common multiple of 765,548,288,991,494 is 820923311520.

LCM Formula to Find Lowest Common Multiple of 765,548,288,991,494

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.

765 x 548 x 288 x 991 x 494 = 59106478429440

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.

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

548 : 1, 2, 4, 137, 274, 548

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

991 : 1, 991

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 765,548,288,991,494, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

548:2x 2x 137

288:2x 2x 2x 2x 2x 3x 3

991:991

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 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 59106478429440/(1x72)

LCM = 59106478429440/72

LCM = 820923311520

Thus, we can understand that the LCM of 765,548,288,991,494 is 820923311520.
