Given numbers are 172, 989, 297, 163

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

Apply this formula for all numbers.

Step1:

LCM(172, 989) = 3956

GCD(172, 989) = ( 172 x 989 ) / 3956

= 172 / 989

= 172

Step2:

LCM(43, 297) = 12771

GCD(43, 297) = ( 43 x 297 ) / 12771

= 43 / 297

= 43

Step3:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

So, Greatest Common Divisor of 172, 989, 297, 163 is 1
