Find LCM of 681,583,635,165,990 with Prime Factorization
3 | 681, 583, 635, 165, 990 |
5 | 227, 583, 635, 55, 330 |
11 | 227, 583, 127, 11, 66 |
227, 53, 127, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 227 x 53 x 127 x 1 x 6 = 1512657630
Therefore, the lowest common multiple of 681,583,635,165,990 is 1512657630.
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.
681 x 583 x 635 x 165 x 990 = 41182103976750
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.
681 : 1, 3, 227, 681
583 : 1, 11, 53, 583
635 : 1, 5, 127, 635
165 : 1, 3, 5, 11, 15, 33, 55, 165
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,583,635,165,990, is 1.
Now, the common factors can be found like this.
681:3x 227
583:11x 53
635:5x 127
165:3x 5x 11
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 11x 11 = 27225
Therefore, the value for common factors is 27225.
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 = 41182103976750/(1x27225)
LCM = 41182103976750/27225
LCM = 1512657630
Thus, we can understand that the LCM of 681,583,635,165,990 is 1512657630.
