Given numbers are 573, 781, 246, 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, 781) = 447513

GCD(573, 781) = ( 573 x 781 ) / 447513

= 573 / 781

= 573

Step2:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 573, 781, 246, 644 is 1
