Given numbers are 644, 809, 837, 174

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

Apply this formula for all numbers.

Step1:

LCM(644, 809) = 520996

GCD(644, 809) = ( 644 x 809 ) / 520996

= 644 / 809

= 644

Step2:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

Step3:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

So, Greatest Common Divisor of 644, 809, 837, 174 is 1
