Given numbers are 653, 623, 672, 261

The list of prime factors of all numbers are

Prime factors of 653 are 653

Prime factors of 623 are 7 x 89

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 653, 623, 672, 261

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

Apply this formula for all numbers.

Step1:

LCM(653, 623) = 406819

GCD(653, 623) = ( 653 x 623 ) / 406819

= 653 / 623

= 653

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 653, 623, 672, 261 is 1
