Given numbers are 788, 655, 183, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 655) = 516140
GCD(788, 655) = ( 788 x 655 ) / 516140
= 788 / 655
= 788
Step2:
LCM(1, 183) = 183
GCD(1, 183) = ( 1 x 183 ) / 183
= 1 / 183
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 788, 655, 183, 620 is 1
