The LCM of 320,769,880,779 is 2108659520.
Find LCM of 320,769,880,779 with Prime Factorization
| 2 | 320, 769, 880, 779 |
| 2 | 160, 769, 440, 779 |
| 2 | 80, 769, 220, 779 |
| 2 | 40, 769, 110, 779 |
| 5 | 20, 769, 55, 779 |
| 4, 769, 11, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 4 x 769 x 11 x 779 = 2108659520
Therefore, the lowest common multiple of 320,769,880,779 is 2108659520.
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.
320 x 769 x 880 x 779 = 168692761600
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
769 : 1, 769
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,769,880,779, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
769:769
880:2x 2x 2x 2x 5x 11
779:19x 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 5 = 80
Therefore, the value for common factors is 80.
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 = 168692761600/(1x80)
LCM = 168692761600/80
LCM = 2108659520
Thus, we can understand that the LCM of 320,769,880,779 is 2108659520.
