Find LCM of 816,473,198,646 with Prime Factorization


2 816, 473, 198, 646
3 408, 473, 99, 323
11 136, 473, 33, 323
17 136, 43, 3, 323
8, 43, 3, 19

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

2 x 3 x 11 x 17 x 8 x 43 x 3 x 19 = 22000176

Therefore, the lowest common multiple of 816,473,198,646 is 22000176.

LCM Formula to Find Lowest Common Multiple of 816,473,198,646

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.

816 x 473 x 198 x 646 = 49368394944

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.

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

473 : 1, 11, 43, 473

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,473,198,646, is 1.

Now, the common factors can be found like this.

816:2x 2x 2x 2x 3x 17

473:11x 43

198:2x 3x 3x 11

646:2x 17x 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 11x 17 = 2244

Therefore, the value for common factors is 2244.

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 = 49368394944/(1x2244)

LCM = 49368394944/2244

LCM = 22000176

Thus, we can understand that the LCM of 816,473,198,646 is 22000176.
