HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 492, 317 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 492, 317 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 492, 317 is 1.

HCF(492, 317) = 1

Highest common factor (HCF) of 492, 317 is 1.

Highest Common Factor of 492,317 using Euclid's algorithm

Highest Common Factor of 492,317 is 1

Step 1: Since 492 > 317, we apply the division lemma to 492 and 317, to get

492 = 317 x 1 + 175

Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 175 and 317, to get

317 = 175 x 1 + 142

Step 3: We consider the new divisor 175 and the new remainder 142, and apply the division lemma to get

175 = 142 x 1 + 33

We consider the new divisor 142 and the new remainder 33,and apply the division lemma to get

142 = 33 x 4 + 10

We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get

33 = 10 x 3 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 492 and 317 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(142,33) = HCF(175,142) = HCF(317,175) = HCF(492,317) .
