What is the common factor for 9 and 17?

1 is your answer!

We found the factors and prime factorization of 9 and 17. The biggest common factor number is the GCF number. So the greatest common factor 9 and 17 is 1.  

Least Common Multiple of 9 and 17 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 9 and 17, than apply into the LCM equation.

GCF(9,17) = 1

LCM(9,17) = ( 9 × 17) / 1

LCM(9,17) = 153 / 1

LCM(9,17) = 153

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
