Find LCM of 765,724,136,448,905 with Prime Factorization
| 2 | 765, 724, 136, 448, 905 |
| 2 | 765, 362, 68, 224, 905 |
| 2 | 765, 181, 34, 112, 905 |
| 5 | 765, 181, 17, 56, 905 |
| 17 | 153, 181, 17, 56, 181 |
| 181 | 9, 181, 1, 56, 181 |
| 9, 1, 1, 56, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 181 x 9 x 1 x 1 x 56 x 1 = 62032320
Therefore, the lowest common multiple of 765,724,136,448,905 is 62032320.
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.
765 x 724 x 136 x 448 x 905 = 30539751782400
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
724 : 1, 2, 4, 181, 362, 724
136 : 1, 2, 4, 8, 17, 34, 68, 136
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,724,136,448,905, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
724:2x 2x 181
136:2x 2x 2x 17
448:2x 2x 2x 2x 2x 2x 7
905:5x 181
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 5x 17x 181 = 492320
Therefore, the value for common factors is 492320.
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 = 30539751782400/(1x492320)
LCM = 30539751782400/492320
LCM = 62032320
Thus, we can understand that the LCM of 765,724,136,448,905 is 62032320.
