Given numbers are 693, 505, 705, 491

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 505 are 5 x 101

Prime factors of 705 are 3 x 5 x 47

Prime factors of 491 are 491

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

Given numbers are 693, 505, 705, 491

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

Apply this formula for all numbers.

Step1:

LCM(693, 505) = 349965

GCD(693, 505) = ( 693 x 505 ) / 349965

= 693 / 505

= 693

Step2:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 693, 505, 705, 491 is 1
