Given numbers are 390, 406, 935, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 406) = 79170
GCD(390, 406) = ( 390 x 406 ) / 79170
= 390 / 406
= 390
Step2:
LCM(2, 935) = 1870
GCD(2, 935) = ( 2 x 935 ) / 1870
= 2 / 935
= 2
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 390, 406, 935, 489 is 1
