Given numbers are 835, 809, 689, 970

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

Apply this formula for all numbers.

Step1:

LCM(835, 809) = 675515

GCD(835, 809) = ( 835 x 809 ) / 675515

= 835 / 809

= 835

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 835, 809, 689, 970 is 1
