Given numbers are 140, 285, 124, 145

The list of prime factors of all numbers are

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

Prime factors of 285 are 3 x 5 x 19

Prime factors of 124 are 2 x 2 x 31

Prime factors of 145 are 5 x 29

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

Given numbers are 140, 285, 124, 145

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

Apply this formula for all numbers.

Step1:

LCM(140, 285) = 7980

GCD(140, 285) = ( 140 x 285 ) / 7980

= 140 / 285

= 140

Step2:

LCM(5, 124) = 620

GCD(5, 124) = ( 5 x 124 ) / 620

= 5 / 124

= 5

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 140, 285, 124, 145 is 1
