Find LCM of 697,979,656,644,656 with Prime Factorization
| 2 | 697, 979, 656, 644, 656 |
| 2 | 697, 979, 328, 322, 328 |
| 2 | 697, 979, 164, 161, 164 |
| 2 | 697, 979, 82, 161, 82 |
| 41 | 697, 979, 41, 161, 41 |
| 17, 979, 1, 161, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 41 x 17 x 979 x 1 x 161 x 1 = 1757767088
Therefore, the lowest common multiple of 697,979,656,644,656 is 1757767088.
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.
697 x 979 x 656 x 644 x 656 = 189107614395392
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.
697 : 1, 17, 41, 697
979 : 1, 11, 89, 979
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,979,656,644,656, is 1.
Now, the common factors can be found like this.
697:17x 41
979:11x 89
656:2x 2x 2x 2x 41
644:2x 2x 7x 23
656:2x 2x 2x 2x 41
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 2x 2x 2x 41x 41 = 107584
Therefore, the value for common factors is 107584.
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 = 189107614395392/(1x107584)
LCM = 189107614395392/107584
LCM = 1757767088
Thus, we can understand that the LCM of 697,979,656,644,656 is 1757767088.
