What is the HCF of 6 and 90?
To find the HCF of two numbers, you first have to express them as the product of their prime factors. In this case we have: 6 = 2x3 90 = 2x3x3x5 The next step is to identify any common factors. In this case both numbers have a 2 and a 3 as a prime factor. Multiply these and you get 6. Thus the HCF of 6 and 90 is 6.
What is the HCF of two prime numbers?
1
What are the HCF of 42 and 90?
The GCF is 6.
I need to know which pair of numbers in relatively prime 10 and 21 or 12 and 54 or 15 and 27 or 21 and 38?
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
What is the common factor of 18 and 90?
HCF is 18
What is the HCF of 6 and 90?

In this case both numbers have a 2 and a 3 as a prime factor. Multiply these and you get 6. Thus the HCF of 6 and 90 is 6.
What are the prime factor of HCF?
Each HCF has its own set of prime factors.
What is the HCF of 4 and 90?
The HCF of 4 and 90 is 2.
What is the HCF of 90 and 210?
The GCF is 30.
HCF FOR66 90 AND 115?
66, 90, & 115 Reduce each number to its prime factors. Hence 66 = 11,3,2 90 = 18,6 = 3,6,6 = 3,3,3,2,2 115 = 5,23 The HCF between 66, & 90 is 3,2 = 6 There is no common factor between 115 and 66,90.
What is the HCF of 90 and 160?
HCF(160, 90) = 10.
What is the HCF of 24 and 90?
Factors of 24: 1,2,3,4,6,8,12 and 24. Factors of 90: 1,2,3,5,9,10,18,30,45 and 90. The HCF (highest common factor) is 3.
What is the HCF of 90 and 126?
The Highest Common Factor (HCF) of 90 and 126 is the largest number that divides both 90 and 126 without leaving a remainder. To find the HCF, we need to determine the common factors of 90 and 126, which are 1, 2, 3, 6, 9, and 18. The largest number among these common factors is 18. Therefore, the HCF of 90 and 126 is 18.
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.
What is the hcf of 90 and 105?
The hcf is 15.
What is 28 and 90 divisible by?
28 and 90 are both divisible by 2, as they are both even numbers. Additionally, 28 is divisible by 4 and 7, while 90 is divisible by 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
What is the HCF of 60 and 90?
30
