Find LCM of 928,968,178,781,116 with Prime Factorization
| 2 | 928, 968, 178, 781, 116 |
| 2 | 464, 484, 89, 781, 58 |
| 2 | 232, 242, 89, 781, 29 |
| 11 | 116, 121, 89, 781, 29 |
| 29 | 116, 11, 89, 71, 29 |
| 4, 11, 89, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 29 x 4 x 11 x 89 x 71 x 1 = 709547872
Therefore, the lowest common multiple of 928,968,178,781,116 is 709547872.
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.
928 x 968 x 178 x 781 x 116 = 14486129354752
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
178 : 1, 2, 89, 178
781 : 1, 11, 71, 781
116 : 1, 2, 4, 29, 58, 116
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,968,178,781,116, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
968:2x 2x 2x 11x 11
178:2x 89
781:11x 71
116:2x 2x 29
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 11x 29 = 20416
Therefore, the value for common factors is 20416.
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 = 14486129354752/(1x20416)
LCM = 14486129354752/20416
LCM = 709547872
Thus, we can understand that the LCM of 928,968,178,781,116 is 709547872.
