Given numbers are 308, 225, 665, 818
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 225) = 69300
GCD(308, 225) = ( 308 x 225 ) / 69300
= 308 / 225
= 308
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
So, Greatest Common Divisor of 308, 225, 665, 818 is 1
