Find LCM of 169,556,561,419,748 with Prime Factorization
| 2 | 169, 556, 561, 419, 748 |
| 2 | 169, 278, 561, 419, 374 |
| 11 | 169, 139, 561, 419, 187 |
| 17 | 169, 139, 51, 419, 17 |
| 169, 139, 3, 419, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 169 x 139 x 3 x 419 x 1 = 22087083876
Therefore, the lowest common multiple of 169,556,561,419,748 is 22087083876.
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.
169 x 556 x 561 x 419 x 748 = 16521138739248
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.
169 : 1, 13, 169
556 : 1, 2, 4, 139, 278, 556
561 : 1, 3, 11, 17, 33, 51, 187, 561
419 : 1, 419
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,556,561,419,748, is 1.
Now, the common factors can be found like this.
169:13x 13
556:2x 2x 139
561:3x 11x 17
419:419
748:2x 2x 11x 17
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 16521138739248/(1x748)
LCM = 16521138739248/748
LCM = 22087083876
Thus, we can understand that the LCM of 169,556,561,419,748 is 22087083876.
