Given numbers are 615,751,561,660,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,751,561,660,121 is 3800225220.
Find LCM of 615,751,561,660,121 with Prime Factorization
3 | 615, 751, 561, 660, 121 |
5 | 205, 751, 187, 220, 121 |
11 | 41, 751, 187, 44, 121 |
41, 751, 17, 4, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 41 x 751 x 17 x 4 x 11 = 3800225220
Therefore, the lowest common multiple of 615,751,561,660,121 is 3800225220.
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.
615 x 751 x 561 x 660 x 121 = 20692226322900
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
751 : 1, 751
561 : 1, 3, 11, 17, 33, 51, 187, 561
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,751,561,660,121, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
751:751
561:3x 11x 17
660:2x 2x 3x 5x 11
121:11x 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 11x 11 = 5445
Therefore, the value for common factors is 5445.
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 = 20692226322900/(1x5445)
LCM = 20692226322900/5445
LCM = 3800225220
Thus, we can understand that the LCM of 615,751,561,660,121 is 3800225220.
