GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 249) = 35109
GCD(423, 249) = ( 423 x 249 ) / 35109
= 423 / 249
= 423
Step2:
LCM(3, 805) = 2415
GCD(3, 805) = ( 3 x 805 ) / 2415
= 3 / 805
= 3
Step3:
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
= 1 / 769
= 1
So, Greatest Common Divisor of 423, 249, 805, 769 is 1
