30
Their highest common factor is 90
Answer is 90
The GCF is 90.
The highest common factor (HCF) of 15, 60, and 90 is 15. To find the HCF, you need to identify the common factors of the numbers and then determine the highest one they share. In this case, the common factors of 15, 60, and 90 are 1, 3, and 15. Since 15 is the highest common factor, it is the HCF of the given numbers.
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.
