The LCM of 291,901,772,720,790 is 959430282480.
Find LCM of 291,901,772,720,790 with Prime Factorization
| 2 | 291, 901, 772, 720, 790 |
| 2 | 291, 901, 386, 360, 395 |
| 3 | 291, 901, 193, 180, 395 |
| 5 | 97, 901, 193, 60, 395 |
| 97, 901, 193, 12, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 97 x 901 x 193 x 12 x 79 = 959430282480
Therefore, the lowest common multiple of 291,901,772,720,790 is 959430282480.
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.
291 x 901 x 772 x 720 x 790 = 115131633897600
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.
291 : 1, 3, 97, 291
901 : 1, 17, 53, 901
772 : 1, 2, 4, 193, 386, 772
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,901,772,720,790, is 1.
Now, the common factors can be found like this.
291:3x 97
901:17x 53
772:2x 2x 193
720:2x 2x 2x 2x 3x 3x 5
790:2x 5x 79
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 5 = 120
Therefore, the value for common factors is 120.
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 = 115131633897600/(1x120)
LCM = 115131633897600/120
LCM = 959430282480
Thus, we can understand that the LCM of 291,901,772,720,790 is 959430282480.
