Given numbers are 949, 143, 920, 168

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

Apply this formula for all numbers.

Step1:

LCM(949, 143) = 10439

GCD(949, 143) = ( 949 x 143 ) / 10439

= 949 / 143

= 949

Step2:

LCM(13, 920) = 11960

GCD(13, 920) = ( 13 x 920 ) / 11960

= 13 / 920

= 13

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 949, 143, 920, 168 is 1
