HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 296, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 991, 296, 549 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 991, 296, 549 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 991, 296, 549 is 1.

HCF(991, 296, 549) = 1

Highest common factor (HCF) of 991, 296, 549 is 1.

Highest Common Factor of 991,296,549 using Euclid's algorithm

Highest Common Factor of 991,296,549 is 1

Step 1: Since 991 > 296, we apply the division lemma to 991 and 296, to get

991 = 296 x 3 + 103

Step 2: Since the reminder 296 ≠ 0, we apply division lemma to 103 and 296, to get

296 = 103 x 2 + 90

Step 3: We consider the new divisor 103 and the new remainder 90, and apply the division lemma to get

103 = 90 x 1 + 13

We consider the new divisor 90 and the new remainder 13,and apply the division lemma to get

90 = 13 x 6 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 296 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(90,13) = HCF(103,90) = HCF(296,103) = HCF(991,296) .

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

Step 1: Since 549 > 1, we apply the division lemma to 549 and 1, to get

549 = 1 x 549 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 549 is 1

Notice that 1 = HCF(549,1) .
