Find LCM of 634,990,143,661,675 with Prime Factorization
| 2 | 634, 990, 143, 661, 675 |
| 3 | 317, 495, 143, 661, 675 |
| 3 | 317, 165, 143, 661, 225 |
| 5 | 317, 55, 143, 661, 75 |
| 11 | 317, 11, 143, 661, 15 |
| 317, 1, 13, 661, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 317 x 1 x 13 x 661 x 15 = 40451117850
Therefore, the lowest common multiple of 634,990,143,661,675 is 40451117850.
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.
634 x 990 x 143 x 661 x 675 = 40046606671500
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.
634 : 1, 2, 317, 634
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
143 : 1, 11, 13, 143
661 : 1, 661
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,990,143,661,675, is 1.
Now, the common factors can be found like this.
634:2x 317
990:2x 3x 3x 5x 11
143:11x 13
661:661
675:3x 3x 3x 5x 5
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 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 40046606671500/(1x990)
LCM = 40046606671500/990
LCM = 40451117850
Thus, we can understand that the LCM of 634,990,143,661,675 is 40451117850.
