Given numbers are 808, 618, 178, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(808, 618) = 249672
GCD(808, 618) = ( 808 x 618 ) / 249672
= 808 / 618
= 808
Step2:
LCM(2, 178) = 178
GCD(2, 178) = ( 2 x 178 ) / 178
= 2 / 178
= 2
Step3:
LCM(2, 665) = 1330
GCD(2, 665) = ( 2 x 665 ) / 1330
= 2 / 665
= 2
So, Greatest Common Divisor of 808, 618, 178, 665 is 1
