Given numbers are 690, 445, 773, 158

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 445 are 5 x 89

Prime factors of 773 are 773

Prime factors of 158 are 2 x 79

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

Given numbers are 690, 445, 773, 158

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

Apply this formula for all numbers.

Step1:

LCM(690, 445) = 61410

GCD(690, 445) = ( 690 x 445 ) / 61410

= 690 / 445

= 690

Step2:

LCM(5, 773) = 3865

GCD(5, 773) = ( 5 x 773 ) / 3865

= 5 / 773

= 5

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 690, 445, 773, 158 is 1
