Given numbers are 361, 530, 489, 248
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 530) = 191330
GCD(361, 530) = ( 361 x 530 ) / 191330
= 361 / 530
= 361
Step2:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
Step3:
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
= 1 / 248
= 1
So, Greatest Common Divisor of 361, 530, 489, 248 is 1
