The list of prime factors of all numbers are
Prime factors of 204 are 2 x 2 x 3 x 17
Prime factors of 637 are 7 x 7 x 13
Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 247 are 13 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 204, 637, 520, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(204, 637) = 129948
GCD(204, 637) = ( 204 x 637 ) / 129948
= 204 / 637
= 204
Step2:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 204, 637, 520, 247 is 1
