Given numbers are 661,645,871,585
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,645,871,585 is 1114039485.
Find LCM of 661,645,871,585 with Prime Factorization
3 | 661, 645, 871, 585 |
5 | 661, 215, 871, 195 |
13 | 661, 43, 871, 39 |
661, 43, 67, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 661 x 43 x 67 x 3 = 1114039485
Therefore, the lowest common multiple of 661,645,871,585 is 1114039485.
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.
661 x 645 x 871 x 585 = 217237699575
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.
661 : 1, 661
645 : 1, 3, 5, 15, 43, 129, 215, 645
871 : 1, 13, 67, 871
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,645,871,585, is 1.
Now, the common factors can be found like this.
661:661
645:3x 5x 43
871:13x 67
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 217237699575/(1x195)
LCM = 217237699575/195
LCM = 1114039485
Thus, we can understand that the LCM of 661,645,871,585 is 1114039485.
