GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 978) = 135942
GCD(417, 978) = ( 417 x 978 ) / 135942
= 417 / 978
= 417
Step2:
LCM(3, 495) = 495
GCD(3, 495) = ( 3 x 495 ) / 495
= 3 / 495
= 3
Step3:
LCM(3, 857) = 2571
GCD(3, 857) = ( 3 x 857 ) / 2571
= 3 / 857
= 3
So, Greatest Common Divisor of 417, 978, 495, 857 is 1
