The LCM of 195,988,371,742 is 5498220.
Find LCM of 195,988,371,742 with Prime Factorization
| 2 | 195, 988, 371, 742 |
| 7 | 195, 494, 371, 371 |
| 13 | 195, 494, 53, 53 |
| 53 | 15, 38, 53, 53 |
| 15, 38, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 53 x 15 x 38 x 1 x 1 = 5498220
Therefore, the lowest common multiple of 195,988,371,742 is 5498220.
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.
195 x 988 x 371 x 742 = 53035830120
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
371 : 1, 7, 53, 371
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,988,371,742, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
988:2x 2x 13x 19
371:7x 53
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13x 53 = 9646
Therefore, the value for common factors is 9646.
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 = 53035830120/(1x9646)
LCM = 53035830120/9646
LCM = 5498220
Thus, we can understand that the LCM of 195,988,371,742 is 5498220.
