Given numbers are 990, 688, 304, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 688) = 340560
GCD(990, 688) = ( 990 x 688 ) / 340560
= 990 / 688
= 990
Step2:
LCM(2, 304) = 304
GCD(2, 304) = ( 2 x 304 ) / 304
= 2 / 304
= 2
Step3:
LCM(2, 605) = 1210
GCD(2, 605) = ( 2 x 605 ) / 1210
= 2 / 605
= 2
So, Greatest Common Divisor of 990, 688, 304, 605 is 1
