Given numbers are 172, 728, 905, 622

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

Apply this formula for all numbers.

Step1:

LCM(172, 728) = 31304

GCD(172, 728) = ( 172 x 728 ) / 31304

= 172 / 728

= 172

Step2:

LCM(4, 905) = 3620

GCD(4, 905) = ( 4 x 905 ) / 3620

= 4 / 905

= 4

Step3:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

So, Greatest Common Divisor of 172, 728, 905, 622 is 1
