Given numbers are 775, 395, 180, 178

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

Apply this formula for all numbers.

Step1:

LCM(775, 395) = 61225

GCD(775, 395) = ( 775 x 395 ) / 61225

= 775 / 395

= 775

Step2:

LCM(5, 180) = 180

GCD(5, 180) = ( 5 x 180 ) / 180

= 5 / 180

= 5

Step3:

LCM(5, 178) = 890

GCD(5, 178) = ( 5 x 178 ) / 890

= 5 / 178

= 5

So, Greatest Common Divisor of 775, 395, 180, 178 is 1
