Given numbers are 645, 771, 554, 227

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

Apply this formula for all numbers.

Step1:

LCM(645, 771) = 165765

GCD(645, 771) = ( 645 x 771 ) / 165765

= 645 / 771

= 645

Step2:

LCM(3, 554) = 1662

GCD(3, 554) = ( 3 x 554 ) / 1662

= 3 / 554

= 3

Step3:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

So, Greatest Common Divisor of 645, 771, 554, 227 is 1
