Given numbers are 28, 23, 83, 19

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

Apply this formula for all numbers.

Step1:

LCM(28, 23) = 644

GCD(28, 23) = ( 28 x 23 ) / 644

= 28 / 23

= 28

Step2:

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

= 1 / 83

= 1

Step3:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

So, Greatest Common Divisor of 28, 23, 83, 19 is 1
