Given numbers are 805, 644, 505, 757

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

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

Prime factors of 505 are 5 x 101

Prime factors of 757 are 757

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

Given numbers are 805, 644, 505, 757

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

Apply this formula for all numbers.

Step1:

LCM(805, 644) = 3220

GCD(805, 644) = ( 805 x 644 ) / 3220

= 805 / 644

= 805

Step2:

LCM(161, 505) = 81305

GCD(161, 505) = ( 161 x 505 ) / 81305

= 161 / 505

= 161

Step3:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

So, Greatest Common Divisor of 805, 644, 505, 757 is 1
