Find LCM of 128,779,836,510,220 with Prime Factorization
| 2 | 128, 779, 836, 510, 220 |
| 2 | 64, 779, 418, 255, 110 |
| 5 | 32, 779, 209, 255, 55 |
| 11 | 32, 779, 209, 51, 11 |
| 19 | 32, 779, 19, 51, 1 |
| 32, 41, 1, 51, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 19 x 32 x 41 x 1 x 51 x 1 = 279692160
Therefore, the lowest common multiple of 128,779,836,510,220 is 279692160.
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.
128 x 779 x 836 x 510 x 220 = 9352905830400
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
779 : 1, 19, 41, 779
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,779,836,510,220, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
779:19x 41
836:2x 2x 11x 19
510:2x 3x 5x 17
220:2x 2x 5x 11
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 5x 11x 19 = 33440
Therefore, the value for common factors is 33440.
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 = 9352905830400/(1x33440)
LCM = 9352905830400/33440
LCM = 279692160
Thus, we can understand that the LCM of 128,779,836,510,220 is 279692160.
