Given numbers are 260, 385, 745, 402

The list of prime factors of all numbers are

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 385 are 5 x 7 x 11

Prime factors of 745 are 5 x 149

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 260, 385, 745, 402

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

Apply this formula for all numbers.

Step1:

LCM(260, 385) = 20020

GCD(260, 385) = ( 260 x 385 ) / 20020

= 260 / 385

= 260

Step2:

LCM(5, 745) = 745

GCD(5, 745) = ( 5 x 745 ) / 745

= 5 / 745

= 5

Step3:

LCM(5, 402) = 2010

GCD(5, 402) = ( 5 x 402 ) / 2010

= 5 / 402

= 5

So, Greatest Common Divisor of 260, 385, 745, 402 is 1
