Given numbers are 645, 694, 97, 911

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

Apply this formula for all numbers.

Step1:

LCM(645, 694) = 447630

GCD(645, 694) = ( 645 x 694 ) / 447630

= 645 / 694

= 645

Step2:

LCM(1, 97) = 97

GCD(1, 97) = ( 1 x 97 ) / 97

= 1 / 97

= 1

Step3:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

So, Greatest Common Divisor of 645, 694, 97, 911 is 1
