Find LCM of 928,160,758,765 with Prime Factorization
| 2 | 928, 160, 758, 765 |
| 2 | 464, 80, 379, 765 |
| 2 | 232, 40, 379, 765 |
| 2 | 116, 20, 379, 765 |
| 2 | 58, 10, 379, 765 |
| 5 | 29, 5, 379, 765 |
| 29, 1, 379, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 29 x 1 x 379 x 153 = 269059680
Therefore, the lowest common multiple of 928,160,758,765 is 269059680.
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.
928 x 160 x 758 x 765 = 86099097600
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
758 : 1, 2, 379, 758
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,160,758,765, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
160:2x 2x 2x 2x 2x 5
758:2x 379
765:3x 3x 5x 17
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 5 = 320
Therefore, the value for common factors is 320.
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 = 86099097600/(1x320)
LCM = 86099097600/320
LCM = 269059680
Thus, we can understand that the LCM of 928,160,758,765 is 269059680.
