Find LCM of 884,988,195,645,421 with Prime Factorization
| 2 | 884, 988, 195, 645, 421 |
| 2 | 442, 494, 195, 645, 421 |
| 3 | 221, 247, 195, 645, 421 |
| 5 | 221, 247, 65, 215, 421 |
| 13 | 221, 247, 13, 43, 421 |
| 17, 19, 1, 43, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 17 x 19 x 1 x 43 x 421 = 4560869820
Therefore, the lowest common multiple of 884,988,195,645,421 is 4560869820.
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.
884 x 988 x 195 x 645 x 421 = 46247219974800
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
195 : 1, 3, 5, 13, 15, 39, 65, 195
645 : 1, 3, 5, 15, 43, 129, 215, 645
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,988,195,645,421, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
988:2x 2x 13x 19
195:3x 5x 13
645:3x 5x 43
421:421
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 5x 13x 13 = 10140
Therefore, the value for common factors is 10140.
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 = 46247219974800/(1x10140)
LCM = 46247219974800/10140
LCM = 4560869820
Thus, we can understand that the LCM of 884,988,195,645,421 is 4560869820.
