Find LCM of 689,429,760,635,786 with Prime Factorization
| 2 | 689, 429, 760, 635, 786 |
| 3 | 689, 429, 380, 635, 393 |
| 5 | 689, 143, 380, 635, 131 |
| 13 | 689, 143, 76, 127, 131 |
| 53, 11, 76, 127, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 53 x 11 x 76 x 127 x 131 = 287489356440
Therefore, the lowest common multiple of 689,429,760,635,786 is 287489356440.
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 429 x 760 x 635 x 786 = 112120849011600
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
635 : 1, 5, 127, 635
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,429,760,635,786, is 1.
Now, the common factors can be found like this.
689:13x 53
429:3x 11x 13
760:2x 2x 2x 5x 19
635:5x 127
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 112120849011600/(1x390)
LCM = 112120849011600/390
LCM = 287489356440
Thus, we can understand that the LCM of 689,429,760,635,786 is 287489356440.
