Question

Can x=2 & y= -3 be the answer to the question - if d is the HCF of 45 and 27.Find x and y satisfying d=45x+ 27y

Answer 1

X=2
Y=3
d= 45x+27y
=45*2+27*(-3)
=90-81=9
Therefore, d=9

We found the factors and prime factorization of 27 and 45. The biggest common factor number is the GCF number.
So the greatest common factor 27 and 45 is 9.
