Find LCM of 816,748,315,661,774 with Prime Factorization
| 2 | 816, 748, 315, 661, 774 |
| 2 | 408, 374, 315, 661, 387 |
| 3 | 204, 187, 315, 661, 387 |
| 3 | 68, 187, 105, 661, 129 |
| 17 | 68, 187, 35, 661, 43 |
| 4, 11, 35, 661, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 4 x 11 x 35 x 661 x 43 = 26788109040
Therefore, the lowest common multiple of 816,748,315,661,774 is 26788109040.
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.
816 x 748 x 315 x 661 x 774 = 98365936394880
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
661 : 1, 661
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,748,315,661,774, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
748:2x 2x 11x 17
315:3x 3x 5x 7
661:661
774:2x 3x 3x 43
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 3x 3x 3x 17 = 3672
Therefore, the value for common factors is 3672.
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 = 98365936394880/(1x3672)
LCM = 98365936394880/3672
LCM = 26788109040
Thus, we can understand that the LCM of 816,748,315,661,774 is 26788109040.
