Given numbers are 628, 954, 991, 166

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

Apply this formula for all numbers.

Step1:

LCM(628, 954) = 299556

GCD(628, 954) = ( 628 x 954 ) / 299556

= 628 / 954

= 628

Step2:

LCM(2, 991) = 1982

GCD(2, 991) = ( 2 x 991 ) / 1982

= 2 / 991

= 2

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 628, 954, 991, 166 is 1
