Given numbers are 140, 180, 281, 161
The list of prime factors of all numbers are
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 180 are 2 x 2 x 3 x 3 x 5
Prime factors of 281 are 281
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 140, 180, 281, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 180) = 1260
GCD(140, 180) = ( 140 x 180 ) / 1260
= 140 / 180
= 140
Step2:
LCM(20, 281) = 5620
GCD(20, 281) = ( 20 x 281 ) / 5620
= 20 / 281
= 20
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 140, 180, 281, 161 is 1
