Given numbers are 620, 437, 253, 478

The list of prime factors of all numbers are

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

Prime factors of 437 are 19 x 23

Prime factors of 253 are 11 x 23

Prime factors of 478 are 2 x 239

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

Given numbers are 620, 437, 253, 478

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

Apply this formula for all numbers.

Step1:

LCM(620, 437) = 270940

GCD(620, 437) = ( 620 x 437 ) / 270940

= 620 / 437

= 620

Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 620, 437, 253, 478 is 1
