Given numbers are 173, 390, 602, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 390) = 67470
GCD(173, 390) = ( 173 x 390 ) / 67470
= 173 / 390
= 173
Step2:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 173, 390, 602, 689 is 1
