HCF of two numbers a & b is b if a is divisible by b.
Here, 90 is divisible by 45 so HCF is 45.
Alternate Methods:
1-
Prime factorization of 45 = 3x3x5
Prime factorization of 90 = 2x3x3x5
From the factorization it is clear that GCF = 3x3x5 = 45
2-
Factors of 45 are 1, 3, 5, 9, 15 & 45.
Factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 30, 45 & 90.
Common factors are 1, 3, 5, 9, 15 and 45 and the greatest common factor is 45.
Oh, dude, the Highest Common Factor (HCF) of 45 and 90 is like the largest number that divides both 45 and 90 evenly. So, you take the factors of each number - 45 is like 1, 3, 5, 9, 15, 45, and 90 is like 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90. The biggest number they both share is 45, so that's the HCF. Easy peasy!
Oh, honey, the highest common factor (HCF) of 45 and 90 is 45. It's like finding the biggest slice of cake you can cut from both numbers without any leftovers. So, in this case, 45 is the winner winner, chicken dinner.
Oh, let's take a moment to appreciate the beauty of numbers! The Highest Common Factor (HCF) of 45 and 90 is 45. You see, the HCF is the largest number that divides evenly into both 45 and 90, like a gentle brushstroke connecting two lovely numbers.

What is the HCF of 12 and 90?
The Highest Common Factor (HCF) of 12 and 90 is 6. To find the HCF, you can list the factors of both numbers and identify the largest number that is common to both lists. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The largest number that appears in both lists is 6, making it the HCF.
What is HCF and LCM of 30 and 45?
To find the HCF you first need to break the numbers down into their prime factors. In this case we have: 30 = 2x3x5 45 = 3x3x5 The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
