Given numbers are 791, 385, 559, 180
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 385) = 43505
GCD(791, 385) = ( 791 x 385 ) / 43505
= 791 / 385
= 791
Step2:
LCM(7, 559) = 3913
GCD(7, 559) = ( 7 x 559 ) / 3913
= 7 / 559
= 7
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 791, 385, 559, 180 is 1
