Given numbers are 965, 180, 680, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(965, 180) = 34740
GCD(965, 180) = ( 965 x 180 ) / 34740
= 965 / 180
= 965
Step2:
LCM(5, 680) = 680
GCD(5, 680) = ( 5 x 680 ) / 680
= 5 / 680
= 5
Step3:
LCM(5, 406) = 2030
GCD(5, 406) = ( 5 x 406 ) / 2030
= 5 / 406
= 5
So, Greatest Common Divisor of 965, 180, 680, 406 is 1
