Given numbers are 221, 715, 545, 123

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 715 are 5 x 11 x 13

Prime factors of 545 are 5 x 109

Prime factors of 123 are 3 x 41

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

Given numbers are 221, 715, 545, 123

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

Apply this formula for all numbers.

Step1:

LCM(221, 715) = 12155

GCD(221, 715) = ( 221 x 715 ) / 12155

= 221 / 715

= 221

Step2:

LCM(13, 545) = 7085

GCD(13, 545) = ( 13 x 545 ) / 7085

= 13 / 545

= 13

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 221, 715, 545, 123 is 1
