Find LCM of 988,621,157,187,198 with Prime Factorization
| 2 | 988, 621, 157, 187, 198 |
| 3 | 494, 621, 157, 187, 99 |
| 3 | 494, 207, 157, 187, 33 |
| 11 | 494, 69, 157, 187, 11 |
| 494, 69, 157, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 494 x 69 x 157 x 17 x 1 = 18013155732
Therefore, the lowest common multiple of 988,621,157,187,198 is 18013155732.
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.
988 x 621 x 157 x 187 x 198 = 3566604834936
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
621 : 1, 3, 9, 23, 27, 69, 207, 621
157 : 1, 157
187 : 1, 11, 17, 187
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,621,157,187,198, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
621:3x 3x 3x 23
157:157
187:11x 17
198:2x 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 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 3566604834936/(1x198)
LCM = 3566604834936/198
LCM = 18013155732
Thus, we can understand that the LCM of 988,621,157,187,198 is 18013155732.
