Find LCM of 796,390,988,205,561 with Prime Factorization
| 2 | 796, 390, 988, 205, 561 |
| 2 | 398, 195, 494, 205, 561 |
| 3 | 199, 195, 247, 205, 561 |
| 5 | 199, 65, 247, 205, 187 |
| 13 | 199, 13, 247, 41, 187 |
| 199, 1, 19, 41, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 199 x 1 x 19 x 41 x 187 = 22611363060
Therefore, the lowest common multiple of 796,390,988,205,561 is 22611363060.
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.
796 x 390 x 988 x 205 x 561 = 35273726373600
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.
796 : 1, 2, 4, 199, 398, 796
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
205 : 1, 5, 41, 205
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 796,390,988,205,561, is 1.
Now, the common factors can be found like this.
796:2x 2x 199
390:2x 3x 5x 13
988:2x 2x 13x 19
205:5x 41
561:3x 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 2x 3x 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 35273726373600/(1x1560)
LCM = 35273726373600/1560
LCM = 22611363060
Thus, we can understand that the LCM of 796,390,988,205,561 is 22611363060.
