GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(571, 685) = 391135
GCD(571, 685) = ( 571 x 685 ) / 391135
= 571 / 685
= 571
Step2:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 571, 685, 853, 121 is 1
