Given numbers are 791, 987, 122, 225

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(791, 987) = 111531

GCD(791, 987) = ( 791 x 987 ) / 111531

= 791 / 987

= 791

Step2:

LCM(7, 122) = 854

GCD(7, 122) = ( 7 x 122 ) / 854

= 7 / 122

= 7

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 791, 987, 122, 225 is 1
