Given numbers are 140, 145, 421, 383

The list of prime factors of all numbers are

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

Prime factors of 145 are 5 x 29

Prime factors of 421 are 421

Prime factors of 383 are 383

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

Given numbers are 140, 145, 421, 383

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

Apply this formula for all numbers.

Step1:

LCM(140, 145) = 4060

GCD(140, 145) = ( 140 x 145 ) / 4060

= 140 / 145

= 140

Step2:

LCM(5, 421) = 2105

GCD(5, 421) = ( 5 x 421 ) / 2105

= 5 / 421

= 5

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 140, 145, 421, 383 is 1
