GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 669) = 190665
GCD(855, 669) = ( 855 x 669 ) / 190665
= 855 / 669
= 855
Step2:
LCM(3, 831) = 831
GCD(3, 831) = ( 3 x 831 ) / 831
= 3 / 831
= 3
Step3:
LCM(3, 567) = 567
GCD(3, 567) = ( 3 x 567 ) / 567
= 3 / 567
= 3
So, Greatest Common Divisor of 855, 669, 831, 567 is 3
