Given numbers are 77, 13, 83, 45

The list of prime factors of all numbers are

Prime factors of 77 are 7 x 11

Prime factors of 13 are 13

Prime factors of 83 are 83

Prime factors of 45 are 3 x 3 x 5

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

Given numbers are 77, 13, 83, 45

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

Apply this formula for all numbers.

Step1:

LCM(77, 13) = 1001

GCD(77, 13) = ( 77 x 13 ) / 1001

= 77 / 13

= 77

Step2:

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

= 1 / 83

= 1

Step3:

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

= 1 / 45

= 1

So, Greatest Common Divisor of 77, 13, 83, 45 is 1
