Given numbers are 791, 305, 995, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 305) = 241255
GCD(791, 305) = ( 791 x 305 ) / 241255
= 791 / 305
= 791
Step2:
LCM(1, 995) = 995
GCD(1, 995) = ( 1 x 995 ) / 995
= 1 / 995
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 791, 305, 995, 620 is 1
