GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 649) = 555544
GCD(856, 649) = ( 856 x 649 ) / 555544
= 856 / 649
= 856
Step2:
LCM(1, 577) = 577
GCD(1, 577) = ( 1 x 577 ) / 577
= 1 / 577
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 856, 649, 577, 487 is 1
