Both 3 and 2 are prime. This means they cannot be broken down further into prime factors. As they are different, this means they will not have any common prime factors. Therefore the HCF of 3 and 2 is 1. The HCF of any two different prime numbers will always be 1.

How can we Find HCF of 144 and 36 by prime factorization method?
Prime factors of 36 are: 2^2 and 3^2 Prime factors of 144 are: 2^4 and 3^2 Prime factors common to both number are 2^2 and 3^2 which when multiplied equals 36 making it the HCF
What is the HCF of 210 and 84?
The GCF is 42.
What is the HCF of 18 36 and 72?
The GCF is 18.
What is the hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
What is the HCF of 18 and 99?
18 = 2 x 3 x 3 99 = 3 x 3 x 11 So hcf = 3 x 3 = 9
What is the HCF of 18 54 and 81?
hcf(18, 54, 81) = 9. Using prime factorization: 18 = 2 x 3^2 54 = 2 x 3^3 81 = 3^4 hcf = 3^2 = 9

What is the HCF of 12 and 66?
12 = 2 x 2 x 3 16 = 2 x 2 x 2 x 2 HCF=2 x 2 = 4 HCF = 4
What is the HCF of 8 and 18?
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
How can we Find HCF of 144 and 36 by prime factorization method?
Prime factors of 36 are: 2^2 and 3^2 Prime factors of 144 are: 2^4 and 3^2 Prime factors common to both number are 2^2 and 3^2 which when multiplied equals 36 making it the HCF
What is the HCF of 210 and 84?
The GCF is 42.
What is the HCF of 18 36 and 72?
The GCF is 18.
How do you find HCF of product of 2 nos?
You find the HCF of the two numbers, not their product. Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the HCF
What 2 numbers have the LCM of 30 and the HCF of 3?
3 and 30.
What is the hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
What is the HCF of 18 and 99?
18 = 2 x 3 x 3 99 = 3 x 3 x 11 So hcf = 3 x 3 = 9
What is the HCF of 16x27x49 and 8x27x125?
hcf(16×27×49, 8×2725) = 8×27 = 216 Using prime factorisation: 16×27×49 = 2⁴ × 3³ × 7² 8×27×125 = 2³ × 3³ × 5³ → hcf = 2³ × 3³ = 8×27 = 216
