Given numbers are 403, 978, 851, 329
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 978) = 394134
GCD(403, 978) = ( 403 x 978 ) / 394134
= 403 / 978
= 403
Step2:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
Step3:
LCM(1, 329) = 329
GCD(1, 329) = ( 1 x 329 ) / 329
= 1 / 329
= 1
So, Greatest Common Divisor of 403, 978, 851, 329 is 1
