Given numbers are 140, 345, 791, 657

The list of prime factors of all numbers are

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

Prime factors of 345 are 3 x 5 x 23

Prime factors of 791 are 7 x 113

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 140, 345, 791, 657

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

Apply this formula for all numbers.

Step1:

LCM(140, 345) = 9660

GCD(140, 345) = ( 140 x 345 ) / 9660

= 140 / 345

= 140

Step2:

LCM(5, 791) = 3955

GCD(5, 791) = ( 5 x 791 ) / 3955

= 5 / 791

= 5

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 140, 345, 791, 657 is 1
