Find LCM of 846,927,418,721 with Prime Factorization
| 2 | 846, 927, 418, 721 |
| 3 | 423, 927, 209, 721 |
| 3 | 141, 309, 209, 721 |
| 103 | 47, 103, 209, 721 |
| 47, 1, 209, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 103 x 47 x 1 x 209 x 7 = 127482894
Therefore, the lowest common multiple of 846,927,418,721 is 127482894.
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.
846 x 927 x 418 x 721 = 236353285476
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
927 : 1, 3, 9, 103, 309, 927
418 : 1, 2, 11, 19, 22, 38, 209, 418
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,927,418,721, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
927:3x 3x 103
418:2x 11x 19
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 103 = 1854
Therefore, the value for common factors is 1854.
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 = 236353285476/(1x1854)
LCM = 236353285476/1854
LCM = 127482894
Thus, we can understand that the LCM of 846,927,418,721 is 127482894.
