Given numbers are 521,869,121,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,869,121,661 is 3291937979.
Find LCM of 521,869,121,661 with Prime Factorization
11 | 521, 869, 121, 661 |
521, 79, 11, 661 |
Multiply the prime numbers at the bottom and the left side.
11 x 521 x 79 x 11 x 661 = 3291937979
Therefore, the lowest common multiple of 521,869,121,661 is 3291937979.
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.
521 x 869 x 121 x 661 = 36211317769
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.
521 : 1, 521
869 : 1, 11, 79, 869
121 : 1, 11, 121
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,869,121,661, is 1.
Now, the common factors can be found like this.
521:521
869:11x 79
121:11x 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.
11 = 11
Therefore, the value for common factors is 11.
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 = 36211317769/(1x11)
LCM = 36211317769/11
LCM = 3291937979
Thus, we can understand that the LCM of 521,869,121,661 is 3291937979.
