The LCM of 198,992,916,651 is 157427424.
Find LCM of 198,992,916,651 with Prime Factorization
| 2 | 198, 992, 916, 651 |
| 2 | 99, 496, 458, 651 |
| 3 | 99, 248, 229, 651 |
| 31 | 33, 248, 229, 217 |
| 33, 8, 229, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 33 x 8 x 229 x 7 = 157427424
Therefore, the lowest common multiple of 198,992,916,651 is 157427424.
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 992 x 916 x 651 = 117126003456
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
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
916 : 1, 2, 4, 229, 458, 916
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,992,916,651, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
992:2x 2x 2x 2x 2x 31
916:2x 2x 229
651:3x 7x 31
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 3x 31 = 744
Therefore, the value for common factors is 744.
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 = 117126003456/(1x744)
LCM = 117126003456/744
LCM = 157427424
Thus, we can understand that the LCM of 198,992,916,651 is 157427424.
