Given numbers are 272, 174, 161, 257
The list of prime factors of all numbers are
Prime factors of 272 are 2 x 2 x 2 x 2 x 17
Prime factors of 174 are 2 x 3 x 29
Prime factors of 161 are 7 x 23
Prime factors of 257 are 257
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 272, 174, 161, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(272, 174) = 23664
GCD(272, 174) = ( 272 x 174 ) / 23664
= 272 / 174
= 272
Step2:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 272, 174, 161, 257 is 1
