Given numbers are 397, 140, 890, 660

The list of prime factors of all numbers are

Prime factors of 397 are 397

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

Prime factors of 890 are 2 x 5 x 89

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

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

Given numbers are 397, 140, 890, 660

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

Apply this formula for all numbers.

Step1:

LCM(397, 140) = 55580

GCD(397, 140) = ( 397 x 140 ) / 55580

= 397 / 140

= 397

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 397, 140, 890, 660 is 1
