Find LCM of 198,135,358,945,778 with Prime Factorization
| 2 | 198, 135, 358, 945, 778 |
| 3 | 99, 135, 179, 945, 389 |
| 3 | 33, 45, 179, 315, 389 |
| 3 | 11, 15, 179, 105, 389 |
| 5 | 11, 5, 179, 35, 389 |
| 11, 1, 179, 7, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 11 x 1 x 179 x 7 x 389 = 1447628490
Therefore, the lowest common multiple of 198,135,358,945,778 is 1447628490.
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 135 x 358 x 945 x 778 = 7035474461400
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
135 : 1, 3, 5, 9, 15, 27, 45, 135
358 : 1, 2, 179, 358
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,135,358,945,778, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
135:3x 3x 3x 5
358:2x 179
945:3x 3x 3x 5x 7
778:2x 389
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 3x 3x 3x 3x 5 = 4860
Therefore, the value for common factors is 4860.
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 = 7035474461400/(1x4860)
LCM = 7035474461400/4860
LCM = 1447628490
Thus, we can understand that the LCM of 198,135,358,945,778 is 1447628490.
