Given numbers are 618, 978, 305, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 978) = 100734
GCD(618, 978) = ( 618 x 978 ) / 100734
= 618 / 978
= 618
Step2:
LCM(6, 305) = 1830
GCD(6, 305) = ( 6 x 305 ) / 1830
= 6 / 305
= 6
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 618, 978, 305, 287 is 1
