Given numbers are 645, 186, 679, 773

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

Apply this formula for all numbers.

Step1:

LCM(645, 186) = 39990

GCD(645, 186) = ( 645 x 186 ) / 39990

= 645 / 186

= 645

Step2:

LCM(3, 679) = 2037

GCD(3, 679) = ( 3 x 679 ) / 2037

= 3 / 679

= 3

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 645, 186, 679, 773 is 1
