Given numbers are 581, 489, 863, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(581, 489) = 284109
GCD(581, 489) = ( 581 x 489 ) / 284109
= 581 / 489
= 581
Step2:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 581, 489, 863, 755 is 1
