Given numbers are 943, 820, 987, 685

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

Apply this formula for all numbers.

Step1:

LCM(943, 820) = 18860

GCD(943, 820) = ( 943 x 820 ) / 18860

= 943 / 820

= 943

Step2:

LCM(41, 987) = 40467

GCD(41, 987) = ( 41 x 987 ) / 40467

= 41 / 987

= 41

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 943, 820, 987, 685 is 1
