Given numbers are 171, 402, 455, 904

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

Apply this formula for all numbers.

Step1:

LCM(171, 402) = 22914

GCD(171, 402) = ( 171 x 402 ) / 22914

= 171 / 402

= 171

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 171, 402, 455, 904 is 1
