Find LCM of 637,691,163,988,548 with Prime Factorization
| 2 | 637, 691, 163, 988, 548 |
| 2 | 637, 691, 163, 494, 274 |
| 13 | 637, 691, 163, 247, 137 |
| 49, 691, 163, 19, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 49 x 691 x 163 x 19 x 137 = 747032065052
Therefore, the lowest common multiple of 637,691,163,988,548 is 747032065052.
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.
637 x 691 x 163 x 988 x 548 = 38845667382704
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.
637 : 1, 7, 13, 49, 91, 637
691 : 1, 691
163 : 1, 163
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
548 : 1, 2, 4, 137, 274, 548
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,691,163,988,548, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
691:691
163:163
988:2x 2x 13x 19
548:2x 2x 137
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 13 = 52
Therefore, the value for common factors is 52.
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 = 38845667382704/(1x52)
LCM = 38845667382704/52
LCM = 747032065052
Thus, we can understand that the LCM of 637,691,163,988,548 is 747032065052.
