Given numbers are 789, 385, 262, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 385) = 303765
GCD(789, 385) = ( 789 x 385 ) / 303765
= 789 / 385
= 789
Step2:
LCM(1, 262) = 262
GCD(1, 262) = ( 1 x 262 ) / 262
= 1 / 262
= 1
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 789, 385, 262, 261 is 1
