Find LCM of 812,968,781,696 with Prime Factorization
| 2 | 812, 968, 781, 696 |
| 2 | 406, 484, 781, 348 |
| 2 | 203, 242, 781, 174 |
| 11 | 203, 121, 781, 87 |
| 29 | 203, 11, 71, 87 |
| 7, 11, 71, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 29 x 7 x 11 x 71 x 3 = 41855352
Therefore, the lowest common multiple of 812,968,781,696 is 41855352.
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.
812 x 968 x 781 x 696 = 427259433216
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
781 : 1, 11, 71, 781
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,968,781,696, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
968:2x 2x 2x 11x 11
781:11x 71
696:2x 2x 2x 3x 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 11x 29 = 10208
Therefore, the value for common factors is 10208.
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 = 427259433216/(1x10208)
LCM = 427259433216/10208
LCM = 41855352
Thus, we can understand that the LCM of 812,968,781,696 is 41855352.
