Given numbers are 159, 421, 602, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 421) = 66939
GCD(159, 421) = ( 159 x 421 ) / 66939
= 159 / 421
= 159
Step2:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 159, 421, 602, 990 is 1
