3 and 108, respectively.
GCF(12, 27) = 3
LCM(12, 27) = 108
Express the numbers in prime factorisation in power form: 12 = 22 x 31 27 = 33 For gcf multiply together the lowest power of the common primes: gcf of 12 and 27 = 31 = 3 For LCM multiply together the highest power of all the primes (across the numbers): LCM of 12 and 27 = 22 x 33 = 108
The GCF of 27 and 81 is 27. And their LCM is 81.
27 and 54, respectively.
Also 18 and 27.
The LCM is 270. The GCF is 3.
27 and 486, respectively.
3 and 675, respectively.
The LCM is: 1,323
27 and 81, respectively.
3 and 54, respectively.
LCM/GCF = 54/9 = 6 So you require two factors of 6 such that their maximum is the smallest. Therefore, rather than 1 and 6, you select 2 and 3. The two numbers are GCF*2 and GCF*3, that is 18 and 27.
The least common multiple of the numbers 12, 28 and 36 is 252.
