Find LCM of 947,816,460,778,912 with Prime Factorization
| 2 | 947, 816, 460, 778, 912 |
| 2 | 947, 408, 230, 389, 456 |
| 2 | 947, 204, 115, 389, 228 |
| 2 | 947, 102, 115, 389, 114 |
| 3 | 947, 51, 115, 389, 57 |
| 947, 17, 115, 389, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 947 x 17 x 115 x 389 x 19 = 656812153680
Therefore, the lowest common multiple of 947,816,460,778,912 is 656812153680.
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.
947 x 816 x 460 x 778 x 912 = 252215867013120
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.
947 : 1, 947
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
778 : 1, 2, 389, 778
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,816,460,778,912, is 1.
Now, the common factors can be found like this.
947:947
816:2x 2x 2x 2x 3x 17
460:2x 2x 5x 23
778:2x 389
912:2x 2x 2x 2x 3x 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 3 = 384
Therefore, the value for common factors is 384.
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 = 252215867013120/(1x384)
LCM = 252215867013120/384
LCM = 656812153680
Thus, we can understand that the LCM of 947,816,460,778,912 is 656812153680.
