HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 233, 399, 45 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 233, 399, 45 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 233, 399, 45 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 233, 399, 45 is 1.

HCF(233, 399, 45) = 1

Highest common factor (HCF) of 233, 399, 45 is 1.

Highest Common Factor of 233,399,45 using Euclid's algorithm

Highest Common Factor of 233,399,45 is 1

Step 1: Since 399 > 233, we apply the division lemma to 399 and 233, to get

399 = 233 x 1 + 166

Step 2: Since the reminder 233 ≠ 0, we apply division lemma to 166 and 233, to get

233 = 166 x 1 + 67

Step 3: We consider the new divisor 166 and the new remainder 67, and apply the division lemma to get

166 = 67 x 2 + 32

We consider the new divisor 67 and the new remainder 32,and apply the division lemma to get

67 = 32 x 2 + 3

We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get

32 = 3 x 10 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 233 and 399 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(67,32) = HCF(166,67) = HCF(233,166) = HCF(399,233) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 45 > 1, we apply the division lemma to 45 and 1, to get

45 = 1 x 45 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 45 is 1

Notice that 1 = HCF(45,1) .
