Given numbers are 401, 286, 978, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 286) = 114686
GCD(401, 286) = ( 401 x 286 ) / 114686
= 401 / 286
= 401
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 401, 286, 978, 965 is 1
