Given numbers are 487, 770, 791, 178

The list of prime factors of all numbers are

Prime factors of 487 are 487

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

Prime factors of 791 are 7 x 113

Prime factors of 178 are 2 x 89

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

Given numbers are 487, 770, 791, 178

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

Apply this formula for all numbers.

Step1:

LCM(487, 770) = 374990

GCD(487, 770) = ( 487 x 770 ) / 374990

= 487 / 770

= 487

Step2:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 487, 770, 791, 178 is 1
