Given numbers are 620, 358, 836, 787

The list of prime factors of all numbers are

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

Prime factors of 358 are 2 x 179

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 787 are 787

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

Given numbers are 620, 358, 836, 787

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

Apply this formula for all numbers.

Step1:

LCM(620, 358) = 110980

GCD(620, 358) = ( 620 x 358 ) / 110980

= 620 / 358

= 620

Step2:

LCM(2, 836) = 836

GCD(2, 836) = ( 2 x 836 ) / 836

= 2 / 836

= 2

Step3:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

So, Greatest Common Divisor of 620, 358, 836, 787 is 1
