The LCM of 154,286,494,387 is 14720706.

Find LCM of 154,286,494,387 with Prime Factorization


2 154, 286, 494, 387
11 77, 143, 247, 387
13 7, 13, 247, 387
7, 1, 19, 387

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

2 x 11 x 13 x 7 x 1 x 19 x 387 = 14720706

Therefore, the lowest common multiple of 154,286,494,387 is 14720706.

LCM Formula to Find Lowest Common Multiple of 154,286,494,387

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.

154 x 286 x 494 x 387 = 8420243832

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.

154 : 1, 2, 7, 11, 14, 22, 77, 154

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

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

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,286,494,387, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

286:2x 11x 13

494:2x 13x 19

387:3x 3x 43

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 13 = 572

Therefore, the value for common factors is 572.

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 = 8420243832/(1x572)

LCM = 8420243832/572

LCM = 14720706

Thus, we can understand that the LCM of 154,286,494,387 is 14720706.
