Given numbers are 691, 320, 90, 885

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

Apply this formula for all numbers.

Step1:

LCM(691, 320) = 221120

GCD(691, 320) = ( 691 x 320 ) / 221120

= 691 / 320

= 691

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

Step3:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

So, Greatest Common Divisor of 691, 320, 90, 885 is 1
