Given numbers are 505, 718, 562, 644

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 718 are 2 x 359

Prime factors of 562 are 2 x 281

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 505, 718, 562, 644

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

Apply this formula for all numbers.

Step1:

LCM(505, 718) = 362590

GCD(505, 718) = ( 505 x 718 ) / 362590

= 505 / 718

= 505

Step2:

LCM(1, 562) = 562

GCD(1, 562) = ( 1 x 562 ) / 562

= 1 / 562

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 505, 718, 562, 644 is 1
