Given numbers are 489, 347, 703, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 347) = 169683
GCD(489, 347) = ( 489 x 347 ) / 169683
= 489 / 347
= 489
Step2:
LCM(1, 703) = 703
GCD(1, 703) = ( 1 x 703 ) / 703
= 1 / 703
= 1
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 489, 347, 703, 765 is 1
