GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 197) = 80573
GCD(409, 197) = ( 409 x 197 ) / 80573
= 409 / 197
= 409
Step2:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
Step3:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
So, Greatest Common Divisor of 409, 197, 612, 860 is 1
