GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 879) = 252273
GCD(287, 879) = ( 287 x 879 ) / 252273
= 287 / 879
= 287
Step2:
LCM(1, 992) = 992
GCD(1, 992) = ( 1 x 992 ) / 992
= 1 / 992
= 1
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 287, 879, 992, 209 is 1
