GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 568) = 60776
GCD(428, 568) = ( 428 x 568 ) / 60776
= 428 / 568
= 428
Step2:
LCM(4, 270) = 540
GCD(4, 270) = ( 4 x 270 ) / 540
= 4 / 270
= 4
Step3:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
So, Greatest Common Divisor of 428, 568, 270, 981 is 1
