HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 497, 263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 423, 497, 263 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 423, 497, 263 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 423, 497, 263 is 1.

HCF(423, 497, 263) = 1

Highest common factor (HCF) of 423, 497, 263 is 1.

Highest Common Factor of 423,497,263 using Euclid's algorithm

Highest Common Factor of 423,497,263 is 1

Step 1: Since 497 > 423, we apply the division lemma to 497 and 423, to get

497 = 423 x 1 + 74

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 74 and 423, to get

423 = 74 x 5 + 53

Step 3: We consider the new divisor 74 and the new remainder 53, and apply the division lemma to get

74 = 53 x 1 + 21

We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get

53 = 21 x 2 + 11

We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get

21 = 11 x 1 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 423 and 497 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(74,53) = HCF(423,74) = HCF(497,423) .

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

Step 1: Since 263 > 1, we apply the division lemma to 263 and 1, to get

263 = 1 x 263 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 263 is 1

Notice that 1 = HCF(263,1) .
