Given numbers are 308, 161, 971, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 161) = 7084
GCD(308, 161) = ( 308 x 161 ) / 7084
= 308 / 161
= 308
Step2:
LCM(7, 971) = 6797
GCD(7, 971) = ( 7 x 971 ) / 6797
= 7 / 971
= 7
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 308, 161, 971, 159 is 1
