30
Their highest common factor is 90
Answer is 90
The GCF is 90.
Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.Since 18 is a factor of 90, it is automatically the GCF.
obviously, its highest common factor is the number itself. so the answer here is 90.
90
6
30
10
9
The Greatest Common Factor (GCF) is: 9
95 and 90's highest common factor is five.
That would be 15. Only a number ending in five would be a factor of 75. 45 is not. 35 is not. 25 is not. 15 is, and it also is a factor of 90. This makes it the highest common factor of 75 and 90, although it is not a prime factor.
hcf(6, 90) = 6.
The GCF of 60 and 90 is 30.
90 and 12's highest common factor is six.
