Given numbers are 89, 97, 28, 38

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

Apply this formula for all numbers.

Step1:

LCM(89, 97) = 8633

GCD(89, 97) = ( 89 x 97 ) / 8633

= 89 / 97

= 89

Step2:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1

Step3:

LCM(1, 38) = 38

GCD(1, 38) = ( 1 x 38 ) / 38

= 1 / 38

= 1

So, Greatest Common Divisor of 89, 97, 28, 38 is 1
