Given numbers are 252, 840, 421, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 840) = 2520
GCD(252, 840) = ( 252 x 840 ) / 2520
= 252 / 840
= 252
Step2:
LCM(84, 421) = 35364
GCD(84, 421) = ( 84 x 421 ) / 35364
= 84 / 421
= 84
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 252, 840, 421, 965 is 1
