Given numbers are 195, 168, 403, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 168) = 10920
GCD(195, 168) = ( 195 x 168 ) / 10920
= 195 / 168
= 195
Step2:
LCM(3, 403) = 1209
GCD(3, 403) = ( 3 x 403 ) / 1209
= 3 / 403
= 3
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 195, 168, 403, 785 is 1
