Find LCM of 789,569,660,242,765 with Prime Factorization
| 2 | 789, 569, 660, 242, 765 |
| 3 | 789, 569, 330, 121, 765 |
| 5 | 263, 569, 110, 121, 255 |
| 11 | 263, 569, 22, 121, 51 |
| 263, 569, 2, 11, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 263 x 569 x 2 x 11 x 51 = 55408298220
Therefore, the lowest common multiple of 789,569,660,242,765 is 55408298220.
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.
789 x 569 x 660 x 242 x 765 = 54854215237800
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.
789 : 1, 3, 263, 789
569 : 1, 569
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
242 : 1, 2, 11, 22, 121, 242
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 789,569,660,242,765, is 1.
Now, the common factors can be found like this.
789:3x 263
569:569
660:2x 2x 3x 5x 11
242:2x 11x 11
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 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 54854215237800/(1x990)
LCM = 54854215237800/990
LCM = 55408298220
Thus, we can understand that the LCM of 789,569,660,242,765 is 55408298220.
