Given numbers are 689, 871, 847, 434

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

Apply this formula for all numbers.

Step1:

LCM(689, 871) = 46163

GCD(689, 871) = ( 689 x 871 ) / 46163

= 689 / 871

= 689

Step2:

LCM(13, 847) = 11011

GCD(13, 847) = ( 13 x 847 ) / 11011

= 13 / 847

= 13

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 689, 871, 847, 434 is 1
