GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 971) = 415588
GCD(428, 971) = ( 428 x 971 ) / 415588
= 428 / 971
= 428
Step2:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
Step3:
LCM(1, 866) = 866
GCD(1, 866) = ( 1 x 866 ) / 866
= 1 / 866
= 1
So, Greatest Common Divisor of 428, 971, 865, 866 is 1
