Given numbers are 420, 548, 189, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 548) = 57540
GCD(420, 548) = ( 420 x 548 ) / 57540
= 420 / 548
= 420
Step2:
LCM(4, 189) = 756
GCD(4, 189) = ( 4 x 189 ) / 756
= 4 / 189
= 4
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 420, 548, 189, 211 is 1
