Given numbers are 418,100,638,198,307
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,100,638,198,307 is 1674654300.
Find LCM of 418,100,638,198,307 with Prime Factorization
| 2 | 418, 100, 638, 198, 307 |
| 11 | 209, 50, 319, 99, 307 |
| 19, 50, 29, 9, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 50 x 29 x 9 x 307 = 1674654300
Therefore, the lowest common multiple of 418,100,638,198,307 is 1674654300.
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.
418 x 100 x 638 x 198 x 307 = 1621065362400
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
638 : 1, 2, 11, 22, 29, 58, 319, 638
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
307 : 1, 307
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,100,638,198,307, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
100:2x 2x 5x 5
638:2x 11x 29
198:2x 3x 3x 11
307:307
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 1621065362400/(1x968)
LCM = 1621065362400/968
LCM = 1674654300
Thus, we can understand that the LCM of 418,100,638,198,307 is 1674654300.
