Given numbers are 93, 23, 91, 81
The list of prime factors of all numbers are
Prime factors of 93 are 3 x 31
Prime factors of 23 are 23
Prime factors of 91 are 7 x 13
Prime factors of 81 are 3 x 3 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 93, 23, 91, 81
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(93, 23) = 2139
GCD(93, 23) = ( 93 x 23 ) / 2139
= 93 / 23
= 93
Step2:
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
= 1 / 91
= 1
Step3:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
So, Greatest Common Divisor of 93, 23, 91, 81 is 1
