Given numbers are 497, 978, 809, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(497, 978) = 486066
GCD(497, 978) = ( 497 x 978 ) / 486066
= 497 / 978
= 497
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 497, 978, 809, 254 is 1
