GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 798) = 74214
GCD(279, 798) = ( 279 x 798 ) / 74214
= 279 / 798
= 279
Step2:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
Step3:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
So, Greatest Common Divisor of 279, 798, 865, 213 is 1
