Given numbers are 140, 518, 155, 279

The list of prime factors of all numbers are

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

Prime factors of 518 are 2 x 7 x 37

Prime factors of 155 are 5 x 31

Prime factors of 279 are 3 x 3 x 31

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

Given numbers are 140, 518, 155, 279

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

Apply this formula for all numbers.

Step1:

LCM(140, 518) = 5180

GCD(140, 518) = ( 140 x 518 ) / 5180

= 140 / 518

= 140

Step2:

LCM(14, 155) = 2170

GCD(14, 155) = ( 14 x 155 ) / 2170

= 14 / 155

= 14

Step3:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

So, Greatest Common Divisor of 140, 518, 155, 279 is 1
