Given numbers are 140, 240, 427, 397

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 427 are 7 x 61

Prime factors of 397 are 397

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

Given numbers are 140, 240, 427, 397

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

Apply this formula for all numbers.

Step1:

LCM(140, 240) = 1680

GCD(140, 240) = ( 140 x 240 ) / 1680

= 140 / 240

= 140

Step2:

LCM(20, 427) = 8540

GCD(20, 427) = ( 20 x 427 ) / 8540

= 20 / 427

= 20

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 140, 240, 427, 397 is 1
