Given numbers are 775, 821, 560, 988

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 821 are 821

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 988 are 2 x 2 x 13 x 19

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

Given numbers are 775, 821, 560, 988

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

Apply this formula for all numbers.

Step1:

LCM(775, 821) = 636275

GCD(775, 821) = ( 775 x 821 ) / 636275

= 775 / 821

= 775

Step2:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 775, 821, 560, 988 is 1
