Given numbers are 970, 860, 28, 691

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

Apply this formula for all numbers.

Step1:

LCM(970, 860) = 83420

GCD(970, 860) = ( 970 x 860 ) / 83420

= 970 / 860

= 970

Step2:

LCM(10, 28) = 140

GCD(10, 28) = ( 10 x 28 ) / 140

= 10 / 28

= 10

Step3:

LCM(2, 691) = 1382

GCD(2, 691) = ( 2 x 691 ) / 1382

= 2 / 691

= 2

So, Greatest Common Divisor of 970, 860, 28, 691 is 1
