Given numbers are 770, 878, 381, 887

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

Apply this formula for all numbers.

Step1:

LCM(770, 878) = 338030

GCD(770, 878) = ( 770 x 878 ) / 338030

= 770 / 878

= 770

Step2:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 770, 878, 381, 887 is 1
