The list of prime factors of all numbers are

Prime factors of 677 are 677

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 402 are 2 x 3 x 67

Prime factors of 489 are 3 x 163

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

Given numbers are 677, 351, 402, 489

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

Apply this formula for all numbers.

Step1:

LCM(677, 351) = 237627

GCD(677, 351) = ( 677 x 351 ) / 237627

= 677 / 351

= 677

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 677, 351, 402, 489 is 1
