Given numbers are 826, 980, 979, 685

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

Apply this formula for all numbers.

Step1:

LCM(826, 980) = 57820

GCD(826, 980) = ( 826 x 980 ) / 57820

= 826 / 980

= 826

Step2:

LCM(14, 979) = 13706

GCD(14, 979) = ( 14 x 979 ) / 13706

= 14 / 979

= 14

Step3:

LCM(1, 685) = 685

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

= 1 / 685

= 1

So, Greatest Common Divisor of 826, 980, 979, 685 is 1
