Find LCM of 640,198,135,634,589 with Prime Factorization
| 2 | 640, 198, 135, 634, 589 |
| 3 | 320, 99, 135, 317, 589 |
| 3 | 320, 33, 45, 317, 589 |
| 5 | 320, 11, 15, 317, 589 |
| 64, 11, 3, 317, 589 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 64 x 11 x 3 x 317 x 589 = 35490407040
Therefore, the lowest common multiple of 640,198,135,634,589 is 35490407040.
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.
640 x 198 x 135 x 634 x 589 = 6388273267200
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
135 : 1, 3, 5, 9, 15, 27, 45, 135
634 : 1, 2, 317, 634
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,198,135,634,589, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
198:2x 3x 3x 11
135:3x 3x 3x 5
634:2x 317
589:19x 31
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 5 = 180
Therefore, the value for common factors is 180.
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 = 6388273267200/(1x180)
LCM = 6388273267200/180
LCM = 35490407040
Thus, we can understand that the LCM of 640,198,135,634,589 is 35490407040.
