Find LCM of 220,961,979,605,772 with Prime Factorization
| 2 | 220, 961, 979, 605, 772 |
| 2 | 110, 961, 979, 605, 386 |
| 5 | 55, 961, 979, 605, 193 |
| 11 | 11, 961, 979, 121, 193 |
| 1, 961, 89, 11, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 1 x 961 x 89 x 11 x 193 = 39947174740
Therefore, the lowest common multiple of 220,961,979,605,772 is 39947174740.
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.
220 x 961 x 979 x 605 x 772 = 96672162870800
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
961 : 1, 31, 961
979 : 1, 11, 89, 979
605 : 1, 5, 11, 55, 121, 605
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,961,979,605,772, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
961:31x 31
979:11x 89
605:5x 11x 11
772:2x 2x 193
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 5x 11x 11 = 2420
Therefore, the value for common factors is 2420.
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 = 96672162870800/(1x2420)
LCM = 96672162870800/2420
LCM = 39947174740
Thus, we can understand that the LCM of 220,961,979,605,772 is 39947174740.
