Given numbers are 254, 922, 20, 945

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

Apply this formula for all numbers.

Step1:

LCM(254, 922) = 117094

GCD(254, 922) = ( 254 x 922 ) / 117094

= 254 / 922

= 254

Step2:

LCM(2, 20) = 20

GCD(2, 20) = ( 2 x 20 ) / 20

= 2 / 20

= 2

Step3:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

So, Greatest Common Divisor of 254, 922, 20, 945 is 1
