GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 489) = 114915
GCD(705, 489) = ( 705 x 489 ) / 114915
= 705 / 489
= 705
Step2:
LCM(3, 296) = 888
GCD(3, 296) = ( 3 x 296 ) / 888
= 3 / 296
= 3
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 705, 489, 296, 915 is 1
