Given numbers are 67, 75, 77, 19

The list of prime factors of all numbers are

Prime factors of 67 are 67

Prime factors of 75 are 3 x 5 x 5

Prime factors of 77 are 7 x 11

Prime factors of 19 are 19

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

Given numbers are 67, 75, 77, 19

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

Apply this formula for all numbers.

Step1:

LCM(67, 75) = 5025

GCD(67, 75) = ( 67 x 75 ) / 5025

= 67 / 75

= 67

Step2:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

Step3:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

So, Greatest Common Divisor of 67, 75, 77, 19 is 1
