Given numbers are 645, 857, 855, 927

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

Apply this formula for all numbers.

Step1:

LCM(645, 857) = 552765

GCD(645, 857) = ( 645 x 857 ) / 552765

= 645 / 857

= 645

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 927) = 927

GCD(1, 927) = ( 1 x 927 ) / 927

= 1 / 927

= 1

So, Greatest Common Divisor of 645, 857, 855, 927 is 1
