Find LCM of 231,274,992,152,721 with Prime Factorization
| 2 | 231, 274, 992, 152, 721 |
| 2 | 231, 137, 496, 76, 721 |
| 2 | 231, 137, 248, 38, 721 |
| 7 | 231, 137, 124, 19, 721 |
| 33, 137, 124, 19, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 33 x 137 x 124 x 19 x 103 = 61437713568
Therefore, the lowest common multiple of 231,274,992,152,721 is 61437713568.
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.
231 x 274 x 992 x 152 x 721 = 6881023919616
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
274 : 1, 2, 137, 274
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
152 : 1, 2, 4, 8, 19, 38, 76, 152
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,274,992,152,721, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
274:2x 137
992:2x 2x 2x 2x 2x 31
152:2x 2x 2x 19
721:7x 103
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 7 = 112
Therefore, the value for common factors is 112.
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 = 6881023919616/(1x112)
LCM = 6881023919616/112
LCM = 61437713568
Thus, we can understand that the LCM of 231,274,992,152,721 is 61437713568.
