Given numbers are 431, 261, 265, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(431, 261) = 112491
GCD(431, 261) = ( 431 x 261 ) / 112491
= 431 / 261
= 431
Step2:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 431, 261, 265, 845 is 1
