Given numbers are 969, 931, 28, 178

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

Apply this formula for all numbers.

Step1:

LCM(969, 931) = 47481

GCD(969, 931) = ( 969 x 931 ) / 47481

= 969 / 931

= 969

Step2:

LCM(19, 28) = 532

GCD(19, 28) = ( 19 x 28 ) / 532

= 19 / 28

= 19

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 969, 931, 28, 178 is 1
