HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 830 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 830 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 497, 830 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 497, 830 is 1.

HCF(497, 830) = 1

HCF of 497, 830 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 497, 830 is 1.

Highest Common Factor of 497,830 using Euclid's algorithm

Highest Common Factor of 497,830 is 1

Step 1: Since 830 > 497, we apply the division lemma to 830 and 497, to get

830 = 497 x 1 + 333

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 333 and 497, to get

497 = 333 x 1 + 164

Step 3: We consider the new divisor 333 and the new remainder 164, and apply the division lemma to get

333 = 164 x 2 + 5

We consider the new divisor 164 and the new remainder 5,and apply the division lemma to get

164 = 5 x 32 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 830 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(164,5) = HCF(333,164) = HCF(497,333) = HCF(830,497) .
