Find LCM of 261,236,628,171,854 with Prime Factorization
| 2 | 261, 236, 628, 171, 854 |
| 2 | 261, 118, 314, 171, 427 |
| 3 | 261, 59, 157, 171, 427 |
| 3 | 87, 59, 157, 57, 427 |
| 29, 59, 157, 19, 427 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 29 x 59 x 157 x 19 x 427 = 78457350636
Therefore, the lowest common multiple of 261,236,628,171,854 is 78457350636.
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.
261 x 236 x 628 x 171 x 854 = 5648929245792
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.
261 : 1, 3, 9, 29, 87, 261
236 : 1, 2, 4, 59, 118, 236
628 : 1, 2, 4, 157, 314, 628
171 : 1, 3, 9, 19, 57, 171
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,236,628,171,854, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
236:2x 2x 59
628:2x 2x 157
171:3x 3x 19
854:2x 7x 61
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 5648929245792/(1x72)
LCM = 5648929245792/72
LCM = 78457350636
Thus, we can understand that the LCM of 261,236,628,171,854 is 78457350636.
