Given numbers are 655, 402, 257, 828

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 402 are 2 x 3 x 67

Prime factors of 257 are 257

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 655, 402, 257, 828

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

Apply this formula for all numbers.

Step1:

LCM(655, 402) = 263310

GCD(655, 402) = ( 655 x 402 ) / 263310

= 655 / 402

= 655

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 655, 402, 257, 828 is 1
