Given numbers are 781, 644, 797, 537

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

Apply this formula for all numbers.

Step1:

LCM(781, 644) = 502964

GCD(781, 644) = ( 781 x 644 ) / 502964

= 781 / 644

= 781

Step2:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

Step3:

LCM(1, 537) = 537

GCD(1, 537) = ( 1 x 537 ) / 537

= 1 / 537

= 1

So, Greatest Common Divisor of 781, 644, 797, 537 is 1
