GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(699, 143) = 99957
GCD(699, 143) = ( 699 x 143 ) / 99957
= 699 / 143
= 699
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 699, 143, 209, 891 is 1
