Find LCM of 747,118,864,272,921 with Prime Factorization
| 2 | 747, 118, 864, 272, 921 |
| 2 | 747, 59, 432, 136, 921 |
| 2 | 747, 59, 216, 68, 921 |
| 2 | 747, 59, 108, 34, 921 |
| 3 | 747, 59, 54, 17, 921 |
| 3 | 249, 59, 18, 17, 307 |
| 83, 59, 6, 17, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 83 x 59 x 6 x 17 x 307 = 22081630752
Therefore, the lowest common multiple of 747,118,864,272,921 is 22081630752.
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.
747 x 118 x 864 x 272 x 921 = 19078528969728
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.
747 : 1, 3, 9, 83, 249, 747
118 : 1, 2, 59, 118
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,118,864,272,921, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
118:2x 59
864:2x 2x 2x 2x 2x 3x 3x 3
272:2x 2x 2x 2x 17
921:3x 307
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 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 19078528969728/(1x864)
LCM = 19078528969728/864
LCM = 22081630752
Thus, we can understand that the LCM of 747,118,864,272,921 is 22081630752.
