Given numbers are 154, 620, 514, 147

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 514 are 2 x 257

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 154, 620, 514, 147

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

Apply this formula for all numbers.

Step1:

LCM(154, 620) = 47740

GCD(154, 620) = ( 154 x 620 ) / 47740

= 154 / 620

= 154

Step2:

LCM(2, 514) = 514

GCD(2, 514) = ( 2 x 514 ) / 514

= 2 / 514

= 2

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 154, 620, 514, 147 is 1
