Find LCM of 198,103,967,721,294 with Prime Factorization
| 2 | 198, 103, 967, 721, 294 |
| 3 | 99, 103, 967, 721, 147 |
| 7 | 33, 103, 967, 721, 49 |
| 103 | 33, 103, 967, 103, 7 |
| 33, 1, 967, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 33 x 1 x 967 x 1 x 7 = 966328902
Therefore, the lowest common multiple of 198,103,967,721,294 is 966328902.
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 103 x 967 x 721 x 294 = 4180338830052
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
103 : 1, 103
967 : 1, 967
721 : 1, 7, 103, 721
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,103,967,721,294, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
103:103
967:967
721:7x 103
294:2x 3x 7x 7
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 7x 103 = 4326
Therefore, the value for common factors is 4326.
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 = 4180338830052/(1x4326)
LCM = 4180338830052/4326
LCM = 966328902
Thus, we can understand that the LCM of 198,103,967,721,294 is 966328902.
