The list of prime factors of all numbers are
Prime factors of 238 are 2 x 7 x 17
Prime factors of 374 are 2 x 11 x 17
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 161 are 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 238, 374, 140, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 374) = 2618
GCD(238, 374) = ( 238 x 374 ) / 2618
= 238 / 374
= 238
Step2:
LCM(34, 140) = 2380
GCD(34, 140) = ( 34 x 140 ) / 2380
= 34 / 140
= 34
Step3:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
So, Greatest Common Divisor of 238, 374, 140, 161 is 1
