Given numbers are 785, 493, 40, 645

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

Apply this formula for all numbers.

Step1:

LCM(785, 493) = 387005

GCD(785, 493) = ( 785 x 493 ) / 387005

= 785 / 493

= 785

Step2:

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

= 1 / 40

= 1

Step3:

LCM(1, 645) = 645

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

= 1 / 645

= 1

So, Greatest Common Divisor of 785, 493, 40, 645 is 1
