Find LCM of 657,312,886,686,154 with Prime Factorization
2 | 657, 312, 886, 686, 154 |
3 | 657, 156, 443, 343, 77 |
7 | 219, 52, 443, 343, 77 |
219, 52, 443, 49, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 219 x 52 x 443 x 49 x 11 = 114206083992
Therefore, the lowest common multiple of 657,312,886,686,154 is 114206083992.
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.
657 x 312 x 886 x 686 x 154 = 19186622110656
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.
657 : 1, 3, 9, 73, 219, 657
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
886 : 1, 2, 443, 886
686 : 1, 2, 7, 14, 49, 98, 343, 686
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,312,886,686,154, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
312:2x 2x 2x 3x 13
886:2x 443
686:2x 7x 7x 7
154:2x 7x 11
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 7 = 168
Therefore, the value for common factors is 168.
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 = 19186622110656/(1x168)
LCM = 19186622110656/168
LCM = 114206083992
Thus, we can understand that the LCM of 657,312,886,686,154 is 114206083992.
