Given numbers are 918, 425, 874, 645

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

Apply this formula for all numbers.

Step1:

LCM(918, 425) = 22950

GCD(918, 425) = ( 918 x 425 ) / 22950

= 918 / 425

= 918

Step2:

LCM(17, 874) = 14858

GCD(17, 874) = ( 17 x 874 ) / 14858

= 17 / 874

= 17

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 918, 425, 874, 645 is 1
