Given numbers are 171, 475, 13, 921

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

Apply this formula for all numbers.

Step1:

LCM(171, 475) = 4275

GCD(171, 475) = ( 171 x 475 ) / 4275

= 171 / 475

= 171

Step2:

LCM(19, 13) = 247

GCD(19, 13) = ( 19 x 13 ) / 247

= 19 / 13

= 19

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 171, 475, 13, 921 is 1
