Given numbers are 172, 997, 43, 646

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

Apply this formula for all numbers.

Step1:

LCM(172, 997) = 171484

GCD(172, 997) = ( 172 x 997 ) / 171484

= 172 / 997

= 172

Step2:

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

= 1 / 43

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 172, 997, 43, 646 is 1
