Given numbers are 822, 868, 78, 869

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

Apply this formula for all numbers.

Step1:

LCM(822, 868) = 356748

GCD(822, 868) = ( 822 x 868 ) / 356748

= 822 / 868

= 822

Step2:

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

= 2 / 78

= 2

Step3:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

So, Greatest Common Divisor of 822, 868, 78, 869 is 1
