Given numbers are 620, 830, 871, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 830) = 51460
GCD(620, 830) = ( 620 x 830 ) / 51460
= 620 / 830
= 620
Step2:
LCM(10, 871) = 8710
GCD(10, 871) = ( 10 x 871 ) / 8710
= 10 / 871
= 10
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 620, 830, 871, 685 is 1
