Find LCM of 281,843,692,703,648 with Prime Factorization
| 2 | 281, 843, 692, 703, 648 |
| 2 | 281, 843, 346, 703, 324 |
| 3 | 281, 843, 173, 703, 162 |
| 281 | 281, 281, 173, 703, 54 |
| 1, 1, 173, 703, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 281 x 1 x 1 x 173 x 703 x 54 = 22145360472
Therefore, the lowest common multiple of 281,843,692,703,648 is 22145360472.
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.
281 x 843 x 692 x 703 x 648 = 74674155511584
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.
281 : 1, 281
843 : 1, 3, 281, 843
692 : 1, 2, 4, 173, 346, 692
703 : 1, 19, 37, 703
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,843,692,703,648, is 1.
Now, the common factors can be found like this.
281:281
843:3x 281
692:2x 2x 173
703:19x 37
648:2x 2x 2x 3x 3x 3x 3
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 3x 281 = 3372
Therefore, the value for common factors is 3372.
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 = 74674155511584/(1x3372)
LCM = 74674155511584/3372
LCM = 22145360472
Thus, we can understand that the LCM of 281,843,692,703,648 is 22145360472.
