Find LCM of 768,221,968,274,351 with Prime Factorization
| 2 | 768, 221, 968, 274, 351 |
| 2 | 384, 221, 484, 137, 351 |
| 2 | 192, 221, 242, 137, 351 |
| 3 | 96, 221, 121, 137, 351 |
| 13 | 32, 221, 121, 137, 117 |
| 32, 17, 121, 137, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 32 x 17 x 121 x 137 x 9 = 25322229504
Therefore, the lowest common multiple of 768,221,968,274,351 is 25322229504.
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.
768 x 221 x 968 x 274 x 351 = 15801071210496
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
221 : 1, 13, 17, 221
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
274 : 1, 2, 137, 274
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,221,968,274,351, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
221:13x 17
968:2x 2x 2x 11x 11
274:2x 137
351:3x 3x 3x 13
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 2x 3x 13 = 624
Therefore, the value for common factors is 624.
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 = 15801071210496/(1x624)
LCM = 15801071210496/624
LCM = 25322229504
Thus, we can understand that the LCM of 768,221,968,274,351 is 25322229504.
