Find LCM of 686,204,427,714 with Prime Factorization


2 686, 204, 427, 714
3 343, 102, 427, 357
7 343, 34, 427, 119
17 49, 34, 61, 17
49, 2, 61, 1

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

2 x 3 x 7 x 17 x 49 x 2 x 61 x 1 = 4268292

Therefore, the lowest common multiple of 686,204,427,714 is 4268292.

LCM Formula to Find Lowest Common Multiple of 686,204,427,714

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.

686 x 204 x 427 x 714 = 42665846832

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

427 : 1, 7, 61, 427

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,204,427,714, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

204:2x 2x 3x 17

427:7x 61

714:2x 3x 7x 17

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 7x 7x 17 = 9996

Therefore, the value for common factors is 9996.

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 = 42665846832/(1x9996)

LCM = 42665846832/9996

LCM = 4268292

Thus, we can understand that the LCM of 686,204,427,714 is 4268292.
