Given numbers are 172, 447, 644, 965

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

Apply this formula for all numbers.

Step1:

LCM(172, 447) = 76884

GCD(172, 447) = ( 172 x 447 ) / 76884

= 172 / 447

= 172

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 172, 447, 644, 965 is 1
