Find LCM of 896,781,748,115,456 with Prime Factorization
| 2 | 896, 781, 748, 115, 456 |
| 2 | 448, 781, 374, 115, 228 |
| 2 | 224, 781, 187, 115, 114 |
| 11 | 112, 781, 187, 115, 57 |
| 112, 71, 17, 115, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 112 x 71 x 17 x 115 x 57 = 77979538560
Therefore, the lowest common multiple of 896,781,748,115,456 is 77979538560.
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.
896 x 781 x 748 x 115 x 456 = 27448797573120
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
781 : 1, 11, 71, 781
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
115 : 1, 5, 23, 115
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,781,748,115,456, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
781:11x 71
748:2x 2x 11x 17
115:5x 23
456:2x 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 11 = 352
Therefore, the value for common factors is 352.
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 = 27448797573120/(1x352)
LCM = 27448797573120/352
LCM = 77979538560
Thus, we can understand that the LCM of 896,781,748,115,456 is 77979538560.
