Find LCM of 660,847,645,242,319 with Prime Factorization
| 2 | 660, 847, 645, 242, 319 |
| 3 | 330, 847, 645, 121, 319 |
| 5 | 110, 847, 215, 121, 319 |
| 11 | 22, 847, 43, 121, 319 |
| 11 | 2, 77, 43, 11, 29 |
| 2, 7, 43, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 11 x 2 x 7 x 43 x 1 x 29 = 63372540
Therefore, the lowest common multiple of 660,847,645,242,319 is 63372540.
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.
660 x 847 x 645 x 242 x 319 = 27835120744200
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.
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
847 : 1, 7, 11, 77, 121, 847
645 : 1, 3, 5, 15, 43, 129, 215, 645
242 : 1, 2, 11, 22, 121, 242
319 : 1, 11, 29, 319
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,847,645,242,319, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
847:7x 11x 11
645:3x 5x 43
242:2x 11x 11
319:11x 29
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 5x 11x 11x 11x 11 = 439230
Therefore, the value for common factors is 439230.
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 = 27835120744200/(1x439230)
LCM = 27835120744200/439230
LCM = 63372540
Thus, we can understand that the LCM of 660,847,645,242,319 is 63372540.
