Find LCM of 925,772,476,420,840 with Prime Factorization
| 2 | 925, 772, 476, 420, 840 |
| 2 | 925, 386, 238, 210, 420 |
| 3 | 925, 193, 119, 105, 210 |
| 5 | 925, 193, 119, 35, 70 |
| 7 | 185, 193, 119, 7, 14 |
| 185, 193, 17, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 185 x 193 x 17 x 1 x 2 = 509867400
Therefore, the lowest common multiple of 925,772,476,420,840 is 509867400.
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.
925 x 772 x 476 x 420 x 840 = 119920812480000
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.
925 : 1, 5, 25, 37, 185, 925
772 : 1, 2, 4, 193, 386, 772
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 925,772,476,420,840, is 1.
Now, the common factors can be found like this.
925:5x 5x 37
772:2x 2x 193
476:2x 2x 7x 17
420:2x 2x 3x 5x 7
840:2x 2x 2x 3x 5x 7
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 2x 2x 3x 5x 5x 7x 7 = 235200
Therefore, the value for common factors is 235200.
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 = 119920812480000/(1x235200)
LCM = 119920812480000/235200
LCM = 509867400
Thus, we can understand that the LCM of 925,772,476,420,840 is 509867400.
