Given numbers are 661,305,839,839
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,305,839,839 is 169146595.
Find LCM of 661,305,839,839 with Prime Factorization
839 | 661, 305, 839, 839 |
661, 305, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
839 x 661 x 305 x 1 x 1 = 169146595
Therefore, the lowest common multiple of 661,305,839,839 is 169146595.
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 305 x 839 x 839 = 141913993205
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
305 : 1, 5, 61, 305
839 : 1, 839
839 : 1, 839
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,305,839,839, is 1.
Now, the common factors can be found like this.
661:661
305:5x 61
839:839
839:839
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
839 = 839
Therefore, the value for common factors is 839.
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 = 141913993205/(1x839)
LCM = 141913993205/839
LCM = 169146595
Thus, we can understand that the LCM of 661,305,839,839 is 169146595.
