Find LCM of 637,971,981,693,793 with Prime Factorization
| 3 | 637, 971, 981, 693, 793 |
| 3 | 637, 971, 327, 231, 793 |
| 7 | 637, 971, 109, 77, 793 |
| 13 | 91, 971, 109, 11, 793 |
| 7, 971, 109, 11, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 13 x 7 x 971 x 109 x 11 x 61 = 407146016277
Therefore, the lowest common multiple of 637,971,981,693,793 is 407146016277.
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 971 x 981 x 693 x 793 = 333452587330863
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
971 : 1, 971
981 : 1, 3, 9, 109, 327, 981
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,971,981,693,793, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
971:971
981:3x 3x 109
693:3x 3x 7x 11
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 13 = 819
Therefore, the value for common factors is 819.
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 = 333452587330863/(1x819)
LCM = 333452587330863/819
LCM = 407146016277
Thus, we can understand that the LCM of 637,971,981,693,793 is 407146016277.
