Find LCM of 688,817,989,136,569 with Prime Factorization
| 2 | 688, 817, 989, 136, 569 |
| 2 | 344, 817, 989, 68, 569 |
| 2 | 172, 817, 989, 34, 569 |
| 43 | 86, 817, 989, 17, 569 |
| 2, 19, 23, 17, 569 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 43 x 2 x 19 x 23 x 17 x 569 = 2908245488
Therefore, the lowest common multiple of 688,817,989,136,569 is 2908245488.
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.
688 x 817 x 989 x 136 x 569 = 43018767258496
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
817 : 1, 19, 43, 817
989 : 1, 23, 43, 989
136 : 1, 2, 4, 8, 17, 34, 68, 136
569 : 1, 569
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,817,989,136,569, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
817:19x 43
989:23x 43
136:2x 2x 2x 17
569:569
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 43x 43 = 14792
Therefore, the value for common factors is 14792.
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 = 43018767258496/(1x14792)
LCM = 43018767258496/14792
LCM = 2908245488
Thus, we can understand that the LCM of 688,817,989,136,569 is 2908245488.
