Given numbers are 390, 493, 530, 867
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 493) = 192270
GCD(390, 493) = ( 390 x 493 ) / 192270
= 390 / 493
= 390
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 867) = 867
GCD(1, 867) = ( 1 x 867 ) / 867
= 1 / 867
= 1
So, Greatest Common Divisor of 390, 493, 530, 867 is 1
