Given numbers are 643, 242, 832, 520

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 242 are 2 x 11 x 11

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

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

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

Given numbers are 643, 242, 832, 520

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

Apply this formula for all numbers.

Step1:

LCM(643, 242) = 155606

GCD(643, 242) = ( 643 x 242 ) / 155606

= 643 / 242

= 643

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 643, 242, 832, 520 is 1
