Given numbers are 644, 711, 831, 943

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

Apply this formula for all numbers.

Step1:

LCM(644, 711) = 457884

GCD(644, 711) = ( 644 x 711 ) / 457884

= 644 / 711

= 644

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

Step3:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

So, Greatest Common Divisor of 644, 711, 831, 943 is 1
