Find the LCM of 661, 220, 661 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 661, 220, 661. So, keep reading to learn more.
Given numbers are 661,220,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,220,661 is 145420.
Find LCM of 661,220,661 with Prime Factorization
661 | 661, 220, 661 |
1, 220, 1 |
Multiply the prime numbers at the bottom and the left side.
661 x 1 x 220 x 1 = 145420
Therefore, the lowest common multiple of 661,220,661 is 145420.
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 220 x 661 = 96122620
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
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,220,661, is 1.
Now, the common factors can be found like this.
661:661
220:2x 2x 5x 11
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
661 = 661
Therefore, the value for common factors is 661.
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 = 96122620/(1x661)
LCM = 96122620/661
LCM = 145420
Thus, we can understand that the LCM of 661,220,661 is 145420.
