Find LCM of 781,461,836,855,116 with Prime Factorization
| 2 | 781, 461, 836, 855, 116 |
| 2 | 781, 461, 418, 855, 58 |
| 11 | 781, 461, 209, 855, 29 |
| 19 | 71, 461, 19, 855, 29 |
| 71, 461, 1, 45, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 71 x 461 x 1 x 45 x 29 = 35708866380
Therefore, the lowest common multiple of 781,461,836,855,116 is 35708866380.
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.
781 x 461 x 836 x 855 x 116 = 29852612293680
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.
781 : 1, 11, 71, 781
461 : 1, 461
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
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 781,461,836,855,116, is 1.
Now, the common factors can be found like this.
781:11x 71
461:461
836:2x 2x 11x 19
855:3x 3x 5x 19
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 11x 19 = 836
Therefore, the value for common factors is 836.
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 = 29852612293680/(1x836)
LCM = 29852612293680/836
LCM = 35708866380
Thus, we can understand that the LCM of 781,461,836,855,116 is 35708866380.
