Given numbers are 436, 686, 847, 697

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

Apply this formula for all numbers.

Step1:

LCM(436, 686) = 149548

GCD(436, 686) = ( 436 x 686 ) / 149548

= 436 / 686

= 436

Step2:

LCM(2, 847) = 1694

GCD(2, 847) = ( 2 x 847 ) / 1694

= 2 / 847

= 2

Step3:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

So, Greatest Common Divisor of 436, 686, 847, 697 is 1
