Given numbers are 755, 689, 620, 303
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(755, 689) = 520195
GCD(755, 689) = ( 755 x 689 ) / 520195
= 755 / 689
= 755
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 303) = 303
GCD(1, 303) = ( 1 x 303 ) / 303
= 1 / 303
= 1
So, Greatest Common Divisor of 755, 689, 620, 303 is 1
