Given numbers are 627,661,121,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 627,661,121,242 is 9117834.
Find LCM of 627,661,121,242 with Prime Factorization
| 11 | 627, 661, 121, 242 |
| 11 | 57, 661, 11, 22 |
| 57, 661, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 57 x 661 x 1 x 2 = 9117834
Therefore, the lowest common multiple of 627,661,121,242 is 9117834.
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.
627 x 661 x 121 x 242 = 12135837054
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.
627 : 1, 3, 11, 19, 33, 57, 209, 627
661 : 1, 661
121 : 1, 11, 121
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,661,121,242, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
661:661
121:11x 11
242:2x 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.
11x 11x 11 = 1331
Therefore, the value for common factors is 1331.
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 = 12135837054/(1x1331)
LCM = 12135837054/1331
LCM = 9117834
Thus, we can understand that the LCM of 627,661,121,242 is 9117834.
