Given numbers are 191,419,630,108,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,419,630,108,838 is 302509620.
Find LCM of 191,419,630,108,838 with Prime Factorization
| 2 | 191, 419, 630, 108, 838 |
| 3 | 191, 419, 315, 54, 419 |
| 3 | 191, 419, 105, 18, 419 |
| 419 | 191, 419, 35, 6, 419 |
| 191, 1, 35, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 419 x 191 x 1 x 35 x 6 x 1 = 302509620
Therefore, the lowest common multiple of 191,419,630,108,838 is 302509620.
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.
191 x 419 x 630 x 108 x 838 = 4563055108080
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.
191 : 1, 191
419 : 1, 419
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
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,419,630,108,838, is 1.
Now, the common factors can be found like this.
191:191
419:419
630:2x 3x 3x 5x 7
108:2x 2x 3x 3x 3
838:2x 419
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 3x 419 = 15084
Therefore, the value for common factors is 15084.
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 = 4563055108080/(1x15084)
LCM = 4563055108080/15084
LCM = 302509620
Thus, we can understand that the LCM of 191,419,630,108,838 is 302509620.
