Given numbers are 878, 788, 868, 775

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

Apply this formula for all numbers.

Step1:

LCM(878, 788) = 345932

GCD(878, 788) = ( 878 x 788 ) / 345932

= 878 / 788

= 878

Step2:

LCM(2, 868) = 868

GCD(2, 868) = ( 2 x 868 ) / 868

= 2 / 868

= 2

Step3:

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

= 2 / 775

= 2

So, Greatest Common Divisor of 878, 788, 868, 775 is 1
