Given numbers are 305, 978, 198, 551
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 978) = 298290
GCD(305, 978) = ( 305 x 978 ) / 298290
= 305 / 978
= 305
Step2:
LCM(1, 198) = 198
GCD(1, 198) = ( 1 x 198 ) / 198
= 1 / 198
= 1
Step3:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
So, Greatest Common Divisor of 305, 978, 198, 551 is 1
