Given numbers are 441, 154, 168, 771

The list of prime factors of all numbers are

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 154 are 2 x 7 x 11

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 771 are 3 x 257

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

Given numbers are 441, 154, 168, 771

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

Apply this formula for all numbers.

Step1:

LCM(441, 154) = 9702

GCD(441, 154) = ( 441 x 154 ) / 9702

= 441 / 154

= 441

Step2:

LCM(7, 168) = 168

GCD(7, 168) = ( 7 x 168 ) / 168

= 7 / 168

= 7

Step3:

LCM(7, 771) = 5397

GCD(7, 771) = ( 7 x 771 ) / 5397

= 7 / 771

= 7

So, Greatest Common Divisor of 441, 154, 168, 771 is 1
