HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 829, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 297, 829, 117 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 297, 829, 117 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 297, 829, 117 is 1.

HCF(297, 829, 117) = 1

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

HCF of:

Highest common factor (HCF) of 297, 829, 117 is 1.

Highest Common Factor of 297,829,117 using Euclid's algorithm

Highest Common Factor of 297,829,117 is 1

Step 1: Since 829 > 297, we apply the division lemma to 829 and 297, to get

829 = 297 x 2 + 235

Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 235 and 297, to get

297 = 235 x 1 + 62

Step 3: We consider the new divisor 235 and the new remainder 62, and apply the division lemma to get

235 = 62 x 3 + 49

We consider the new divisor 62 and the new remainder 49,and apply the division lemma to get

62 = 49 x 1 + 13

We consider the new divisor 49 and the new remainder 13,and apply the division lemma to get

49 = 13 x 3 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 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 297 and 829 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(62,49) = HCF(235,62) = HCF(297,235) = HCF(829,297) .

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

Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get

117 = 1 x 117 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1

Notice that 1 = HCF(117,1) .
