Given numbers are 434, 420, 252, 711
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(434, 420) = 13020
GCD(434, 420) = ( 434 x 420 ) / 13020
= 434 / 420
= 434
Step2:
LCM(14, 252) = 252
GCD(14, 252) = ( 14 x 252 ) / 252
= 14 / 252
= 14
Step3:
LCM(14, 711) = 9954
GCD(14, 711) = ( 14 x 711 ) / 9954
= 14 / 711
= 14
So, Greatest Common Divisor of 434, 420, 252, 711 is 1
