Find LCM of 625,771,442,925,720 with Prime Factorization
| 2 | 625, 771, 442, 925, 720 |
| 3 | 625, 771, 221, 925, 360 |
| 5 | 625, 257, 221, 925, 120 |
| 5 | 125, 257, 221, 185, 24 |
| 25, 257, 221, 37, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 25 x 257 x 221 x 37 x 24 = 189134010000
Therefore, the lowest common multiple of 625,771,442,925,720 is 189134010000.
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.
625 x 771 x 442 x 925 x 720 = 141850507500000
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.
625 : 1, 5, 25, 125, 625
771 : 1, 3, 257, 771
442 : 1, 2, 13, 17, 26, 34, 221, 442
925 : 1, 5, 25, 37, 185, 925
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,771,442,925,720, is 1.
Now, the common factors can be found like this.
625:5x 5x 5x 5
771:3x 257
442:2x 13x 17
925:5x 5x 37
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 3x 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 141850507500000/(1x750)
LCM = 141850507500000/750
LCM = 189134010000
Thus, we can understand that the LCM of 625,771,442,925,720 is 189134010000.
