HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 897, 403, 770 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 897, 403, 770 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 897, 403, 770 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 897, 403, 770 is 1.

HCF(897, 403, 770) = 1

HCF of 897, 403, 770 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 897, 403, 770 is 1.

Highest Common Factor of 897,403,770 using Euclid's algorithm

Highest Common Factor of 897,403,770 is 1

Step 1: Since 897 > 403, we apply the division lemma to 897 and 403, to get

897 = 403 x 2 + 91

Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 91 and 403, to get

403 = 91 x 4 + 39

Step 3: We consider the new divisor 91 and the new remainder 39, and apply the division lemma to get

91 = 39 x 2 + 13

We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get

39 = 13 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 897 and 403 is 13

Notice that 13 = HCF(39,13) = HCF(91,39) = HCF(403,91) = HCF(897,403) .

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

Step 1: Since 770 > 13, we apply the division lemma to 770 and 13, to get

770 = 13 x 59 + 3

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 3 and 13, to get

13 = 3 x 4 + 1

Step 3: 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 13 and 770 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(770,13) .
