Given numbers are 742, 395, 660, 245

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 395 are 5 x 79

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 742, 395, 660, 245

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

Apply this formula for all numbers.

Step1:

LCM(742, 395) = 293090

GCD(742, 395) = ( 742 x 395 ) / 293090

= 742 / 395

= 742

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 742, 395, 660, 245 is 1
