GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(177, 255) = 15045
GCD(177, 255) = ( 177 x 255 ) / 15045
= 177 / 255
= 177
Step2:
LCM(3, 949) = 2847
GCD(3, 949) = ( 3 x 949 ) / 2847
= 3 / 949
= 3
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 177, 255, 949, 770 is 1
