Find LCM of 646,956,711,992,304 with Prime Factorization
| 2 | 646, 956, 711, 992, 304 |
| 2 | 323, 478, 711, 496, 152 |
| 2 | 323, 239, 711, 248, 76 |
| 2 | 323, 239, 711, 124, 38 |
| 19 | 323, 239, 711, 62, 19 |
| 17, 239, 711, 62, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 17 x 239 x 711 x 62 x 1 = 54447970464
Therefore, the lowest common multiple of 646,956,711,992,304 is 54447970464.
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.
646 x 956 x 711 x 992 x 304 = 132417464168448
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
956 : 1, 2, 4, 239, 478, 956
711 : 1, 3, 9, 79, 237, 711
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,956,711,992,304, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
956:2x 2x 239
711:3x 3x 79
992:2x 2x 2x 2x 2x 31
304:2x 2x 2x 2x 19
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 19 = 2432
Therefore, the value for common factors is 2432.
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 = 132417464168448/(1x2432)
LCM = 132417464168448/2432
LCM = 54447970464
Thus, we can understand that the LCM of 646,956,711,992,304 is 54447970464.
