Given numbers are 344, 402, 416, 645

The list of prime factors of all numbers are

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 402 are 2 x 3 x 67

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 344, 402, 416, 645

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

Apply this formula for all numbers.

Step1:

LCM(344, 402) = 69144

GCD(344, 402) = ( 344 x 402 ) / 69144

= 344 / 402

= 344

Step2:

LCM(2, 416) = 416

GCD(2, 416) = ( 2 x 416 ) / 416

= 2 / 416

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 344, 402, 416, 645 is 1
