Given numbers are 640, 236, 720, 823

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 236 are 2 x 2 x 59

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 823 are 823

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

Given numbers are 640, 236, 720, 823

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

Apply this formula for all numbers.

Step1:

LCM(640, 236) = 37760

GCD(640, 236) = ( 640 x 236 ) / 37760

= 640 / 236

= 640

Step2:

LCM(4, 720) = 720

GCD(4, 720) = ( 4 x 720 ) / 720

= 4 / 720

= 4

Step3:

LCM(4, 823) = 3292

GCD(4, 823) = ( 4 x 823 ) / 3292

= 4 / 823

= 4

So, Greatest Common Divisor of 640, 236, 720, 823 is 1
