Given numbers are 31, 45, 44, 80
The list of prime factors of all numbers are
Prime factors of 31 are 31
Prime factors of 45 are 3 x 3 x 5
Prime factors of 44 are 2 x 2 x 11
Prime factors of 80 are 2 x 2 x 2 x 2 x 5
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 31, 45, 44, 80 using LCM Formula
Given numbers are 31, 45, 44, 80
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(31, 45) = 1395
GCD(31, 45) = ( 31 x 45 ) / 1395
= 31 / 45
= 31
Step2:
LCM(1, 44) = 44
GCD(1, 44) = ( 1 x 44 ) / 44
= 1 / 44
= 1
Step3:
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
= 1 / 80
= 1
So, Greatest Common Divisor of 31, 45, 44, 80 is 1
