Given numbers are 485, 403, 618, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 403) = 195455
GCD(485, 403) = ( 485 x 403 ) / 195455
= 485 / 403
= 485
Step2:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 485, 403, 618, 163 is 1
