HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 692, 809, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 692, 809, 51 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 692, 809, 51 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 692, 809, 51 is 1.

HCF(692, 809, 51) = 1

Highest common factor (HCF) of 692, 809, 51 is 1.

Highest Common Factor of 692,809,51 using Euclid's algorithm

Highest Common Factor of 692,809,51 is 1

Step 1: Since 809 > 692, we apply the division lemma to 809 and 692, to get

809 = 692 x 1 + 117

Step 2: Since the reminder 692 ≠ 0, we apply division lemma to 117 and 692, to get

692 = 117 x 5 + 107

Step 3: We consider the new divisor 117 and the new remainder 107, and apply the division lemma to get

117 = 107 x 1 + 10

We consider the new divisor 107 and the new remainder 10,and apply the division lemma to get

107 = 10 x 10 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 692 and 809 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(107,10) = HCF(117,107) = HCF(692,117) = HCF(809,692) .


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

Step 1: Since 51 > 1, we apply the division lemma to 51 and 1, to get

51 = 1 x 51 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 51 is 1

Notice that 1 = HCF(51,1) .
