Given numbers are 428, 917, 178, 275

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

Apply this formula for all numbers.

Step1:

LCM(428, 917) = 392476

GCD(428, 917) = ( 428 x 917 ) / 392476

= 428 / 917

= 428

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

So, Greatest Common Divisor of 428, 917, 178, 275 is 1
