Given numbers are 690, 699, 871, 682
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 699) = 160770
GCD(690, 699) = ( 690 x 699 ) / 160770
= 690 / 699
= 690
Step2:
LCM(3, 871) = 2613
GCD(3, 871) = ( 3 x 871 ) / 2613
= 3 / 871
= 3
Step3:
LCM(1, 682) = 682
GCD(1, 682) = ( 1 x 682 ) / 682
= 1 / 682
= 1
So, Greatest Common Divisor of 690, 699, 871, 682 is 1
