Given numbers are 261, 958, 161, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 958) = 250038
GCD(261, 958) = ( 261 x 958 ) / 250038
= 261 / 958
= 261
Step2:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
Step3:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
So, Greatest Common Divisor of 261, 958, 161, 917 is 1
