Given numbers are 645, 774, 277, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 774) = 3870
GCD(645, 774) = ( 645 x 774 ) / 3870
= 645 / 774
= 645
Step2:
LCM(129, 277) = 35733
GCD(129, 277) = ( 129 x 277 ) / 35733
= 129 / 277
= 129
Step3:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
So, Greatest Common Divisor of 645, 774, 277, 185 is 1
