Given numbers are 645, 276, 171, 567

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

Apply this formula for all numbers.

Step1:

LCM(645, 276) = 59340

GCD(645, 276) = ( 645 x 276 ) / 59340

= 645 / 276

= 645

Step2:

LCM(3, 171) = 171

GCD(3, 171) = ( 3 x 171 ) / 171

= 3 / 171

= 3

Step3:

LCM(3, 567) = 567

GCD(3, 567) = ( 3 x 567 ) / 567

= 3 / 567

= 3

So, Greatest Common Divisor of 645, 276, 171, 567 is 3
