Given numbers are 661,661,502,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,661,502,991 is 328835602.
Find LCM of 661,661,502,991 with Prime Factorization
661 | 661, 661, 502, 991 |
1, 1, 502, 991 |
Multiply the prime numbers at the bottom and the left side.
661 x 1 x 1 x 502 x 991 = 328835602
Therefore, the lowest common multiple of 661,661,502,991 is 328835602.
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 661 x 502 x 991 = 217360332922
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
661 : 1, 661
502 : 1, 2, 251, 502
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,661,502,991, is 1.
Now, the common factors can be found like this.
661:661
661:661
502:2x 251
991:991
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 = 217360332922/(1x661)
LCM = 217360332922/661
LCM = 328835602
Thus, we can understand that the LCM of 661,661,502,991 is 328835602.
