Given numbers are 720, 496, 618, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 496) = 22320
GCD(720, 496) = ( 720 x 496 ) / 22320
= 720 / 496
= 720
Step2:
LCM(16, 618) = 4944
GCD(16, 618) = ( 16 x 618 ) / 4944
= 16 / 618
= 16
Step3:
LCM(2, 489) = 978
GCD(2, 489) = ( 2 x 489 ) / 978
= 2 / 489
= 2
So, Greatest Common Divisor of 720, 496, 618, 489 is 1
