The answer is 1, my friend.
The GCF is 1.
The GCF is 27.
The GCF is 27.
The GCF of 27 and 81 is 27. And their LCM is 81.
The GCF is 27.
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, 135 is 27.
The GCF is 27.
The GCF is 22.
The GCF is 22.
The Greatest Common Factor (GCF) of 27, 81, and 54 is 27.
