Find LCM of 220,945,924,656,291 with Prime Factorization
| 2 | 220, 945, 924, 656, 291 |
| 2 | 110, 945, 462, 328, 291 |
| 3 | 55, 945, 231, 164, 291 |
| 5 | 55, 315, 77, 164, 97 |
| 7 | 11, 63, 77, 164, 97 |
| 11 | 11, 9, 11, 164, 97 |
| 1, 9, 1, 164, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 1 x 9 x 1 x 164 x 97 = 661454640
Therefore, the lowest common multiple of 220,945,924,656,291 is 661454640.
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.
220 x 945 x 924 x 656 x 291 = 36671045241600
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,945,924,656,291, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
945:3x 3x 3x 5x 7
924:2x 2x 3x 7x 11
656:2x 2x 2x 2x 41
291:3x 97
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 3x 5x 7x 11 = 55440
Therefore, the value for common factors is 55440.
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 = 36671045241600/(1x55440)
LCM = 36671045241600/55440
LCM = 661454640
Thus, we can understand that the LCM of 220,945,924,656,291 is 661454640.
