Given numbers are 520, 610, 21, 993

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 610 are 2 x 5 x 61

Prime factors of 21 are 3 x 7

Prime factors of 993 are 3 x 331

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

Given numbers are 520, 610, 21, 993

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

Apply this formula for all numbers.

Step1:

LCM(520, 610) = 31720

GCD(520, 610) = ( 520 x 610 ) / 31720

= 520 / 610

= 520

Step2:

LCM(10, 21) = 210

GCD(10, 21) = ( 10 x 21 ) / 210

= 10 / 21

= 10

Step3:

LCM(1, 993) = 993

GCD(1, 993) = ( 1 x 993 ) / 993

= 1 / 993

= 1

So, Greatest Common Divisor of 520, 610, 21, 993 is 1
