Given numbers are 261, 787, 421, 293
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 787) = 205407
GCD(261, 787) = ( 261 x 787 ) / 205407
= 261 / 787
= 261
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 293) = 293
GCD(1, 293) = ( 1 x 293 ) / 293
= 1 / 293
= 1
So, Greatest Common Divisor of 261, 787, 421, 293 is 1
