Given numbers are 198,630,909,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,630,909,918 is 35696430.
Find LCM of 198,630,909,918 with Prime Factorization
| 2 | 198, 630, 909, 918 |
| 3 | 99, 315, 909, 459 |
| 3 | 33, 105, 303, 153 |
| 11, 35, 101, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 35 x 101 x 51 = 35696430
Therefore, the lowest common multiple of 198,630,909,918 is 35696430.
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.
198 x 630 x 909 x 918 = 104090789880
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
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
909 : 1, 3, 9, 101, 303, 909
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,630,909,918, is 9.
Now, the common factors can be found like this.
198:2x 3x 3x 11
630:2x 3x 3x 5x 7
909:3x 3x 101
918:2x 3x 3x 3x 17
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 104090789880/(9x324)
LCM = 104090789880/2916
LCM = 35696430
Thus, we can understand that the LCM of 198,630,909,918 is 35696430.
