Given numbers are 766, 254, 640, 161

The list of prime factors of all numbers are

Prime factors of 766 are 2 x 383

Prime factors of 254 are 2 x 127

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 161 are 7 x 23

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

Given numbers are 766, 254, 640, 161

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

Apply this formula for all numbers.

Step1:

LCM(766, 254) = 97282

GCD(766, 254) = ( 766 x 254 ) / 97282

= 766 / 254

= 766

Step2:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

Step3:

LCM(2, 161) = 322

GCD(2, 161) = ( 2 x 161 ) / 322

= 2 / 161

= 2

So, Greatest Common Divisor of 766, 254, 640, 161 is 1
