Given numbers are 777, 257, 201, 520

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 257 are 257

Prime factors of 201 are 3 x 67

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 777, 257, 201, 520

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

Apply this formula for all numbers.

Step1:

LCM(777, 257) = 199689

GCD(777, 257) = ( 777 x 257 ) / 199689

= 777 / 257

= 777

Step2:

LCM(1, 201) = 201

GCD(1, 201) = ( 1 x 201 ) / 201

= 1 / 201

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 777, 257, 201, 520 is 1
