Given numbers are 402, 770, 452, 641

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 452 are 2 x 2 x 113

Prime factors of 641 are 641

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

Given numbers are 402, 770, 452, 641

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

Apply this formula for all numbers.

Step1:

LCM(402, 770) = 154770

GCD(402, 770) = ( 402 x 770 ) / 154770

= 402 / 770

= 402

Step2:

LCM(2, 452) = 452

GCD(2, 452) = ( 2 x 452 ) / 452

= 2 / 452

= 2

Step3:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

So, Greatest Common Divisor of 402, 770, 452, 641 is 1
