Given numbers are 775, 245, 161, 969

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

Apply this formula for all numbers.

Step1:

LCM(775, 245) = 37975

GCD(775, 245) = ( 775 x 245 ) / 37975

= 775 / 245

= 775

Step2:

LCM(5, 161) = 805

GCD(5, 161) = ( 5 x 161 ) / 805

= 5 / 161

= 5

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 775, 245, 161, 969 is 1
