Given numbers are 869, 824, 638, 668

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

Apply this formula for all numbers.

Step1:

LCM(869, 824) = 716056

GCD(869, 824) = ( 869 x 824 ) / 716056

= 869 / 824

= 869

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 869, 824, 638, 668 is 1
