Given numbers are 573, 457, 644

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

Apply this formula for all numbers.

Step1:

LCM(573, 457) = 261861

GCD(573, 457) = ( 573 x 457 ) / 261861

= 573 / 457

= 573

Step2:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 573, 457, 644 is 1
