HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 791 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 298, 791 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 298, 791 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 298, 791 is 1.

HCF(298, 791) = 1

Highest Common Factor of 298,791 using Euclid's algorithm

Highest Common Factor of 298,791 is 1

Step 1: Since 791 > 298, we apply the division lemma to 791 and 298, to get

791 = 298 x 2 + 195

Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 195 and 298, to get

298 = 195 x 1 + 103

Step 3: We consider the new divisor 195 and the new remainder 103, and apply the division lemma to get

195 = 103 x 1 + 92

We consider the new divisor 103 and the new remainder 92,and apply the division lemma to get

103 = 92 x 1 + 11

We consider the new divisor 92 and the new remainder 11,and apply the division lemma to get

92 = 11 x 8 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 298 and 791 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(92,11) = HCF(103,92) = HCF(195,103) = HCF(298,195) = HCF(791,298) .
