Find LCM of 256,784,807,458,420 with Prime Factorization
| 2 | 256, 784, 807, 458, 420 |
| 2 | 128, 392, 807, 229, 210 |
| 2 | 64, 196, 807, 229, 105 |
| 2 | 32, 98, 807, 229, 105 |
| 3 | 16, 49, 807, 229, 105 |
| 7 | 16, 49, 269, 229, 35 |
| 16, 7, 269, 229, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 16 x 7 x 269 x 229 x 5 = 11590844160
Therefore, the lowest common multiple of 256,784,807,458,420 is 11590844160.
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 784 x 807 x 458 x 420 = 31156189102080
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
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
807 : 1, 3, 269, 807
458 : 1, 2, 229, 458
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,784,807,458,420, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
784:2x 2x 2x 2x 7x 7
807:3x 269
458:2x 229
420:2x 2x 3x 5x 7
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 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 31156189102080/(1x2688)
LCM = 31156189102080/2688
LCM = 11590844160
Thus, we can understand that the LCM of 256,784,807,458,420 is 11590844160.
