Given numbers are 771, 408, 743, 653

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 743 are 743

Prime factors of 653 are 653

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

Given numbers are 771, 408, 743, 653

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

Apply this formula for all numbers.

Step1:

LCM(771, 408) = 104856

GCD(771, 408) = ( 771 x 408 ) / 104856

= 771 / 408

= 771

Step2:

LCM(3, 743) = 2229

GCD(3, 743) = ( 3 x 743 ) / 2229

= 3 / 743

= 3

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 771, 408, 743, 653 is 1
