Given numbers are 689, 293, 816, 125

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

Apply this formula for all numbers.

Step1:

LCM(689, 293) = 201877

GCD(689, 293) = ( 689 x 293 ) / 201877

= 689 / 293

= 689

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

So, Greatest Common Divisor of 689, 293, 816, 125 is 1
