Find LCM of 256,712,780,384 with Prime Factorization
2 | 256, 712, 780, 384 |
2 | 128, 356, 390, 192 |
2 | 64, 178, 195, 96 |
2 | 32, 89, 195, 48 |
2 | 16, 89, 195, 24 |
2 | 8, 89, 195, 12 |
2 | 4, 89, 195, 6 |
3 | 2, 89, 195, 3 |
2, 89, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 2 x 89 x 65 x 1 = 4442880
Therefore, the lowest common multiple of 256,712,780,384 is 4442880.
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.
256 x 712 x 780 x 384 = 54594109440
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
712 : 1, 2, 4, 8, 89, 178, 356, 712
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,712,780,384, is 4.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
712:2x 2x 2x 89
780:2x 2x 3x 5x 13
384:2x 2x 2x 2x 2x 2x 2x 3
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 2x 2x 2x 2x 2x 3 = 3072
Therefore, the value for common factors is 3072.
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 = 54594109440/(4x3072)
LCM = 54594109440/12288
LCM = 4442880
Thus, we can understand that the LCM of 256,712,780,384 is 4442880.
