Given numbers are 640, 346, 526, 621

The list of prime factors of all numbers are

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

Prime factors of 346 are 2 x 173

Prime factors of 526 are 2 x 263

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 640, 346, 526, 621

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

Apply this formula for all numbers.

Step1:

LCM(640, 346) = 110720

GCD(640, 346) = ( 640 x 346 ) / 110720

= 640 / 346

= 640

Step2:

LCM(2, 526) = 526

GCD(2, 526) = ( 2 x 526 ) / 526

= 2 / 526

= 2

Step3:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

So, Greatest Common Divisor of 640, 346, 526, 621 is 1
