Given numbers are 287, 780, 737, 454

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 737 are 11 x 67

Prime factors of 454 are 2 x 227

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

Given numbers are 287, 780, 737, 454

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

Apply this formula for all numbers.

Step1:

LCM(287, 780) = 223860

GCD(287, 780) = ( 287 x 780 ) / 223860

= 287 / 780

= 287

Step2:

LCM(1, 737) = 737

GCD(1, 737) = ( 1 x 737 ) / 737

= 1 / 737

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 287, 780, 737, 454 is 1
