Given numbers are 371, 929, 781, 645

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

Apply this formula for all numbers.

Step1:

LCM(371, 929) = 344659

GCD(371, 929) = ( 371 x 929 ) / 344659

= 371 / 929

= 371

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 371, 929, 781, 645 is 1
