Find LCM of 779,279,288,428,561 with Prime Factorization
| 2 | 779, 279, 288, 428, 561 |
| 2 | 779, 279, 144, 214, 561 |
| 3 | 779, 279, 72, 107, 561 |
| 3 | 779, 93, 24, 107, 187 |
| 779, 31, 8, 107, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 779 x 31 x 8 x 107 x 187 = 139160834208
Therefore, the lowest common multiple of 779,279,288,428,561 is 139160834208.
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.
779 x 279 x 288 x 428 x 561 = 15029370094464
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.
779 : 1, 19, 41, 779
279 : 1, 3, 9, 31, 93, 279
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
428 : 1, 2, 4, 107, 214, 428
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 779,279,288,428,561, is 1.
Now, the common factors can be found like this.
779:19x 41
279:3x 3x 31
288:2x 2x 2x 2x 2x 3x 3
428:2x 2x 107
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 15029370094464/(1x108)
LCM = 15029370094464/108
LCM = 139160834208
Thus, we can understand that the LCM of 779,279,288,428,561 is 139160834208.
