Given numbers are 645, 922, 397, 177

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

Apply this formula for all numbers.

Step1:

LCM(645, 922) = 594690

GCD(645, 922) = ( 645 x 922 ) / 594690

= 645 / 922

= 645

Step2:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

Step3:

LCM(1, 177) = 177

GCD(1, 177) = ( 1 x 177 ) / 177

= 1 / 177

= 1

So, Greatest Common Divisor of 645, 922, 397, 177 is 1
