Given numbers are 722, 767, 828, 428

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 767 are 13 x 59

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 722, 767, 828, 428

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

Apply this formula for all numbers.

Step1:

LCM(722, 767) = 553774

GCD(722, 767) = ( 722 x 767 ) / 553774

= 722 / 767

= 722

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 722, 767, 828, 428 is 1
