what is the GCF of two different prime numbers explain
Answered by emma
GCF of two natural numbers is three and there 180 is one of the numbers is 75 a number example find second number
Answered by oobleck
not sure what the "three and there" means, but
75 = 3^1 5^2
180 = 2^2 3^2 5^1
sorry. Since 5^2 is not a factor of 180, it cannot be the LCM of 75 and any other number
Answered by oobleck
sorry. I read LCM, not GCF
GCF(75,180) = 3*5 = 15
Answered by oobleck
GCF of two primes is 1, since they have no other factors.
