Given numbers are 402, 206, 620, 265

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 206 are 2 x 103

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 265 are 5 x 53

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

Given numbers are 402, 206, 620, 265

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

Apply this formula for all numbers.

Step1:

LCM(402, 206) = 41406

GCD(402, 206) = ( 402 x 206 ) / 41406

= 402 / 206

= 402

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 265) = 530

GCD(2, 265) = ( 2 x 265 ) / 530

= 2 / 265

= 2

So, Greatest Common Divisor of 402, 206, 620, 265 is 1
