Given numbers are 620, 978, 785, 495

The list of prime factors of all numbers are

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

Prime factors of 978 are 2 x 3 x 163

Prime factors of 785 are 5 x 157

Prime factors of 495 are 3 x 3 x 5 x 11

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

Given numbers are 620, 978, 785, 495

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

Apply this formula for all numbers.

Step1:

LCM(620, 978) = 303180

GCD(620, 978) = ( 620 x 978 ) / 303180

= 620 / 978

= 620

Step2:

LCM(2, 785) = 1570

GCD(2, 785) = ( 2 x 785 ) / 1570

= 2 / 785

= 2

Step3:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

So, Greatest Common Divisor of 620, 978, 785, 495 is 1
