HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 853, 68 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 691, 853, 68 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 691, 853, 68 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 691, 853, 68 is 1.

HCF(691, 853, 68) = 1

Highest common factor (HCF) of 691, 853, 68 is 1.

Highest Common Factor of 691,853,68 using Euclid's algorithm

Highest Common Factor of 691,853,68 is 1

Step 1: Since 853 > 691, we apply the division lemma to 853 and 691, to get

853 = 691 x 1 + 162

Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 162 and 691, to get

691 = 162 x 4 + 43

Step 3: We consider the new divisor 162 and the new remainder 43, and apply the division lemma to get

162 = 43 x 3 + 33

We consider the new divisor 43 and the new remainder 33,and apply the division lemma to get

43 = 33 x 1 + 10

We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get

33 = 10 x 3 + 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 691 and 853 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(43,33) = HCF(162,43) = HCF(691,162) = HCF(853,691) .

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

Step 1: Since 68 > 1, we apply the division lemma to 68 and 1, to get

68 = 1 x 68 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 68 is 1

Notice that 1 = HCF(68,1) .
