Find LCM of 689,288,772,149,657 with Prime Factorization
| 2 | 689, 288, 772, 149, 657 |
| 2 | 689, 144, 386, 149, 657 |
| 3 | 689, 72, 193, 149, 657 |
| 3 | 689, 24, 193, 149, 219 |
| 689, 8, 193, 149, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 689 x 8 x 193 x 149 x 73 = 416560558752
Therefore, the lowest common multiple of 689,288,772,149,657 is 416560558752.
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.
689 x 288 x 772 x 149 x 657 = 14996180115072
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.
689 : 1, 13, 53, 689
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
772 : 1, 2, 4, 193, 386, 772
149 : 1, 149
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,288,772,149,657, is 1.
Now, the common factors can be found like this.
689:13x 53
288:2x 2x 2x 2x 2x 3x 3
772:2x 2x 193
149:149
657:3x 3x 73
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 3 = 36
Therefore, the value for common factors is 36.
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 = 14996180115072/(1x36)
LCM = 14996180115072/36
LCM = 416560558752
Thus, we can understand that the LCM of 689,288,772,149,657 is 416560558752.
