Given numbers are 620, 687, 787, 219

The list of prime factors of all numbers are

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

Prime factors of 687 are 3 x 229

Prime factors of 787 are 787

Prime factors of 219 are 3 x 73

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

Given numbers are 620, 687, 787, 219

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

Apply this formula for all numbers.

Step1:

LCM(620, 687) = 425940

GCD(620, 687) = ( 620 x 687 ) / 425940

= 620 / 687

= 620

Step2:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 620, 687, 787, 219 is 1
