GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(284, 209) = 59356
GCD(284, 209) = ( 284 x 209 ) / 59356
= 284 / 209
= 284
Step2:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 284, 209, 885, 891 is 1
