Given numbers are 878, 408, 712, 787

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

Apply this formula for all numbers.

Step1:

LCM(878, 408) = 179112

GCD(878, 408) = ( 878 x 408 ) / 179112

= 878 / 408

= 878

Step2:

LCM(2, 712) = 712

GCD(2, 712) = ( 2 x 712 ) / 712

= 2 / 712

= 2

Step3:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

So, Greatest Common Divisor of 878, 408, 712, 787 is 1
