Find LCM of 825,140,491,792 with Prime Factorization
| 2 | 825, 140, 491, 792 |
| 2 | 825, 70, 491, 396 |
| 3 | 825, 35, 491, 198 |
| 5 | 275, 35, 491, 66 |
| 11 | 55, 7, 491, 66 |
| 5, 7, 491, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 5 x 7 x 491 x 6 = 68052600
Therefore, the lowest common multiple of 825,140,491,792 is 68052600.
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.
825 x 140 x 491 x 792 = 44914716000
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
491 : 1, 491
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,140,491,792, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
140:2x 2x 5x 7
491:491
792:2x 2x 2x 3x 3x 11
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 44914716000/(1x660)
LCM = 44914716000/660
LCM = 68052600
Thus, we can understand that the LCM of 825,140,491,792 is 68052600.
