The list of prime factors of all numbers are
Prime factors of 538 are 2 x 269
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 249 are 3 x 83
Prime factors of 351 are 3 x 3 x 3 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 538, 780, 249, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(538, 780) = 209820
GCD(538, 780) = ( 538 x 780 ) / 209820
= 538 / 780
= 538
Step2:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 538, 780, 249, 351 is 1
