HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 736, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 986, 736, 697 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 986, 736, 697 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 986, 736, 697 is 1.

HCF(986, 736, 697) = 1

Highest Common Factor of 986,736,697 using Euclid's algorithm

Highest Common Factor of 986,736,697 is 1

Step 1: Since 986 > 736, we apply the division lemma to 986 and 736, to get

986 = 736 x 1 + 250

Step 2: Since the reminder 736 ≠ 0, we apply division lemma to 250 and 736, to get

736 = 250 x 2 + 236

Step 3: We consider the new divisor 250 and the new remainder 236, and apply the division lemma to get

250 = 236 x 1 + 14

We consider the new divisor 236 and the new remainder 14,and apply the division lemma to get

236 = 14 x 16 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 736 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(236,14) = HCF(250,236) = HCF(736,250) = HCF(986,736) .

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

Step 1: Since 697 > 2, we apply the division lemma to 697 and 2, to get

697 = 2 x 348 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 697 is 1

Notice that 1 = HCF(2,1) = HCF(697,2) .
