Respuesta :
The GCF is the greatest common factor that go into the three numbers 45, 18 and 39,
3 into 45 is 15
3 into 18 is 6
3 into 39 is 13
There is no other number that can go simultaneously into 15, 6 and 13.
So the GCF of 45, 18 and 39 is 3.
3 into 45 is 15
3 into 18 is 6
3 into 39 is 13
There is no other number that can go simultaneously into 15, 6 and 13.
So the GCF of 45, 18 and 39 is 3.
