Find LCM of 255,921,263,490,147 with Prime Factorization
| 3 | 255, 921, 263, 490, 147 |
| 5 | 85, 307, 263, 490, 49 |
| 7 | 17, 307, 263, 98, 49 |
| 7 | 17, 307, 263, 14, 7 |
| 17, 307, 263, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 7 x 17 x 307 x 263 x 2 x 1 = 2017717590
Therefore, the lowest common multiple of 255,921,263,490,147 is 2017717590.
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.
255 x 921 x 263 x 490 x 147 = 4449067285950
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
921 : 1, 3, 307, 921
263 : 1, 263
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,921,263,490,147, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
921:3x 307
263:263
490:2x 5x 7x 7
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7x 7 = 2205
Therefore, the value for common factors is 2205.
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 = 4449067285950/(1x2205)
LCM = 4449067285950/2205
LCM = 2017717590
Thus, we can understand that the LCM of 255,921,263,490,147 is 2017717590.
