Given numbers are 771, 172, 945, 554

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 172 are 2 x 2 x 43

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 554 are 2 x 277

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

Given numbers are 771, 172, 945, 554

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

Apply this formula for all numbers.

Step1:

LCM(771, 172) = 132612

GCD(771, 172) = ( 771 x 172 ) / 132612

= 771 / 172

= 771

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 771, 172, 945, 554 is 1
