The LCM of 717,882,669,612,720 is 31965408720.
Find LCM of 717,882,669,612,720 with Prime Factorization
| 2 | 717, 882, 669, 612, 720 |
| 2 | 717, 441, 669, 306, 360 |
| 3 | 717, 441, 669, 153, 180 |
| 3 | 239, 147, 223, 51, 60 |
| 239, 49, 223, 17, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 239 x 49 x 223 x 17 x 20 = 31965408720
Therefore, the lowest common multiple of 717,882,669,612,720 is 31965408720.
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.
717 x 882 x 669 x 612 x 720 = 186422263655040
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.
717 : 1, 3, 239, 717
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
669 : 1, 3, 223, 669
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,882,669,612,720, is 3.
Now, the common factors can be found like this.
717:3x 239
882:2x 3x 3x 7x 7
669:3x 223
612:2x 2x 3x 3x 17
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 3x 3x 3 = 1944
Therefore, the value for common factors is 1944.
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 = 186422263655040/(3x1944)
LCM = 186422263655040/5832
LCM = 31965408720
Thus, we can understand that the LCM of 717,882,669,612,720 is 31965408720.
