Find LCM of 916,451,986,748,745 with Prime Factorization
| 2 | 916, 451, 986, 748, 745 |
| 2 | 458, 451, 493, 374, 745 |
| 11 | 229, 451, 493, 187, 745 |
| 17 | 229, 41, 493, 17, 745 |
| 229, 41, 29, 1, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 229 x 41 x 29 x 1 x 745 = 151731310060
Therefore, the lowest common multiple of 916,451,986,748,745 is 151731310060.
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.
916 x 451 x 986 x 748 x 745 = 226990039849760
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.
916 : 1, 2, 4, 229, 458, 916
451 : 1, 11, 41, 451
986 : 1, 2, 17, 29, 34, 58, 493, 986
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,451,986,748,745, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
451:11x 41
986:2x 17x 29
748:2x 2x 11x 17
745:5x 149
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 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 226990039849760/(1x1496)
LCM = 226990039849760/1496
LCM = 151731310060
Thus, we can understand that the LCM of 916,451,986,748,745 is 151731310060.
