Given numbers are 791, 504, 487, 221

The list of prime factors of all numbers are

Prime factors of 791 are 7 x 113

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 487 are 487

Prime factors of 221 are 13 x 17

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

Given numbers are 791, 504, 487, 221

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

Apply this formula for all numbers.

Step1:

LCM(791, 504) = 56952

GCD(791, 504) = ( 791 x 504 ) / 56952

= 791 / 504

= 791

Step2:

LCM(7, 487) = 3409

GCD(7, 487) = ( 7 x 487 ) / 3409

= 7 / 487

= 7

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 791, 504, 487, 221 is 1
