Given numbers are 869, 638, 247, 851

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

Apply this formula for all numbers.

Step1:

LCM(869, 638) = 50402

GCD(869, 638) = ( 869 x 638 ) / 50402

= 869 / 638

= 869

Step2:

LCM(11, 247) = 2717

GCD(11, 247) = ( 11 x 247 ) / 2717

= 11 / 247

= 11

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 869, 638, 247, 851 is 1
