Given numbers are 690, 800, 198, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 800) = 55200
GCD(690, 800) = ( 690 x 800 ) / 55200
= 690 / 800
= 690
Step2:
LCM(10, 198) = 990
GCD(10, 198) = ( 10 x 198 ) / 990
= 10 / 198
= 10
Step3:
LCM(2, 808) = 808
GCD(2, 808) = ( 2 x 808 ) / 808
= 2 / 808
= 2
So, Greatest Common Divisor of 690, 800, 198, 808 is 2
