Given numbers are 775, 770, 420, 887

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 887 are 887

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 775, 770, 420, 887

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

Apply this formula for all numbers.

Step1:

LCM(775, 770) = 119350

GCD(775, 770) = ( 775 x 770 ) / 119350

= 775 / 770

= 775

Step2:

LCM(5, 420) = 420

GCD(5, 420) = ( 5 x 420 ) / 420

= 5 / 420

= 5

Step3:

LCM(5, 887) = 4435

GCD(5, 887) = ( 5 x 887 ) / 4435

= 5 / 887

= 5

So, Greatest Common Divisor of 775, 770, 420, 887 is 1
