Given numbers are 644, 571, 637, 373

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

Apply this formula for all numbers.

Step1:

LCM(644, 571) = 367724

GCD(644, 571) = ( 644 x 571 ) / 367724

= 644 / 571

= 644

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

= 1 / 373

= 1

So, Greatest Common Divisor of 644, 571, 637, 373 is 1
