Given numbers are 997, 140, 86, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(997, 140) = 139580
GCD(997, 140) = ( 997 x 140 ) / 139580
= 997 / 140
= 997
Step2:
LCM(1, 86) = 86
GCD(1, 86) = ( 1 x 86 ) / 86
= 1 / 86
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 997, 140, 86, 489 is 1
