Find LCM of 630,483,690,831 with Prime Factorization
| 2 | 630, 483, 690, 831 |
| 3 | 315, 483, 345, 831 |
| 5 | 105, 161, 115, 277 |
| 7 | 21, 161, 23, 277 |
| 23 | 3, 23, 23, 277 |
| 3, 1, 1, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 3 x 1 x 1 x 277 = 4013730
Therefore, the lowest common multiple of 630,483,690,831 is 4013730.
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.
630 x 483 x 690 x 831 = 174476843100
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
483 : 1, 3, 7, 21, 23, 69, 161, 483
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
831 : 1, 3, 277, 831
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,483,690,831, is 3.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
483:3x 7x 23
690:2x 3x 5x 23
831:3x 277
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 3x 5x 7x 23 = 14490
Therefore, the value for common factors is 14490.
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 = 174476843100/(3x14490)
LCM = 174476843100/43470
LCM = 4013730
Thus, we can understand that the LCM of 630,483,690,831 is 4013730.
