Given numbers are 530, 287, 522, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 287) = 152110
GCD(530, 287) = ( 530 x 287 ) / 152110
= 530 / 287
= 530
Step2:
LCM(1, 522) = 522
GCD(1, 522) = ( 1 x 522 ) / 522
= 1 / 522
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 530, 287, 522, 390 is 1
