Find LCM of 684,279,676,720,725 with Prime Factorization
| 2 | 684, 279, 676, 720, 725 |
| 2 | 342, 279, 338, 360, 725 |
| 3 | 171, 279, 169, 180, 725 |
| 3 | 57, 93, 169, 60, 725 |
| 5 | 19, 31, 169, 20, 725 |
| 19, 31, 169, 4, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 31 x 169 x 4 x 145 = 10392080400
Therefore, the lowest common multiple of 684,279,676,720,725 is 10392080400.
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.
684 x 279 x 676 x 720 x 725 = 67340680992000
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
279 : 1, 3, 9, 31, 93, 279
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
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
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,279,676,720,725, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
279:3x 3x 31
676:2x 2x 13x 13
720:2x 2x 2x 2x 3x 3x 5
725:5x 5x 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 2x 2x 2x 3x 3x 3x 3x 5 = 6480
Therefore, the value for common factors is 6480.
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 = 67340680992000/(1x6480)
LCM = 67340680992000/6480
LCM = 10392080400
Thus, we can understand that the LCM of 684,279,676,720,725 is 10392080400.
