Find LCM of 198,221,748,795,716 with Prime Factorization
| 2 | 198, 221, 748, 795, 716 |
| 2 | 99, 221, 374, 795, 358 |
| 3 | 99, 221, 187, 795, 179 |
| 11 | 33, 221, 187, 265, 179 |
| 17 | 3, 221, 17, 265, 179 |
| 3, 13, 1, 265, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 3 x 13 x 1 x 265 x 179 = 4151321460
Therefore, the lowest common multiple of 198,221,748,795,716 is 4151321460.
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 221 x 748 x 795 x 716 = 18631130712480
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
221 : 1, 13, 17, 221
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
795 : 1, 3, 5, 15, 53, 159, 265, 795
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,221,748,795,716, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
221:13x 17
748:2x 2x 11x 17
795:3x 5x 53
716:2x 2x 179
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 11x 17 = 4488
Therefore, the value for common factors is 4488.
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 = 18631130712480/(1x4488)
LCM = 18631130712480/4488
LCM = 4151321460
Thus, we can understand that the LCM of 198,221,748,795,716 is 4151321460.
