Given numbers are 423, 777, 717, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 777) = 109557
GCD(423, 777) = ( 423 x 777 ) / 109557
= 423 / 777
= 423
Step2:
LCM(3, 717) = 717
GCD(3, 717) = ( 3 x 717 ) / 717
= 3 / 717
= 3
Step3:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
So, Greatest Common Divisor of 423, 777, 717, 865 is 1
