Given numbers are 611,380,138,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,380,138,561 is 2995818540.
Find LCM of 611,380,138,561 with Prime Factorization
2 | 611, 380, 138, 561 |
3 | 611, 190, 69, 561 |
611, 190, 23, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 611 x 190 x 23 x 187 = 2995818540
Therefore, the lowest common multiple of 611,380,138,561 is 2995818540.
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.
611 x 380 x 138 x 561 = 17974911240
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.
611 : 1, 13, 47, 611
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
138 : 1, 2, 3, 6, 23, 46, 69, 138
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,380,138,561, is 1.
Now, the common factors can be found like this.
611:13x 47
380:2x 2x 5x 19
138:2x 3x 23
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 17974911240/(1x6)
LCM = 17974911240/6
LCM = 2995818540
Thus, we can understand that the LCM of 611,380,138,561 is 2995818540.
