Find LCM of 800,688,165,704,172 with Prime Factorization
| 2 | 800, 688, 165, 704, 172 |
| 2 | 400, 344, 165, 352, 86 |
| 2 | 200, 172, 165, 176, 43 |
| 2 | 100, 86, 165, 88, 43 |
| 2 | 50, 43, 165, 44, 43 |
| 5 | 25, 43, 165, 22, 43 |
| 11 | 5, 43, 33, 22, 43 |
| 43 | 5, 43, 3, 2, 43 |
| 5, 1, 3, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 11 x 43 x 5 x 1 x 3 x 2 x 1 = 2270400
Therefore, the lowest common multiple of 800,688,165,704,172 is 2270400.
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.
800 x 688 x 165 x 704 x 172 = 10996727808000
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
165 : 1, 3, 5, 11, 15, 33, 55, 165
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,688,165,704,172, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
688:2x 2x 2x 2x 43
165:3x 5x 11
704:2x 2x 2x 2x 2x 2x 11
172:2x 2x 43
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 2x 2x 2x 2x 2x 2x 5x 11x 43 = 4843520
Therefore, the value for common factors is 4843520.
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 = 10996727808000/(1x4843520)
LCM = 10996727808000/4843520
LCM = 2270400
Thus, we can understand that the LCM of 800,688,165,704,172 is 2270400.
