GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 685) = 356885
GCD(521, 685) = ( 521 x 685 ) / 356885
= 521 / 685
= 521
Step2:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 521, 685, 878, 428 is 1
