Given numbers are 583, 642, 790, 645

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

Apply this formula for all numbers.

Step1:

LCM(583, 642) = 374286

GCD(583, 642) = ( 583 x 642 ) / 374286

= 583 / 642

= 583

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 645) = 645

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

= 1 / 645

= 1

So, Greatest Common Divisor of 583, 642, 790, 645 is 1
