HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 673, 331 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 801, 673, 331 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 801, 673, 331 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 801, 673, 331 is 1.

HCF(801, 673, 331) = 1

Highest common factor (HCF) of 801, 673, 331 is 1.

Highest Common Factor of 801,673,331 using Euclid's algorithm

Highest Common Factor of 801,673,331 is 1

Step 1: Since 801 > 673, we apply the division lemma to 801 and 673, to get

801 = 673 x 1 + 128

Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 128 and 673, to get

673 = 128 x 5 + 33

Step 3: We consider the new divisor 128 and the new remainder 33, and apply the division lemma to get

128 = 33 x 3 + 29

We consider the new divisor 33 and the new remainder 29,and apply the division lemma to get

33 = 29 x 1 + 4

We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get

29 = 4 x 7 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 801 and 673 is 1

Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(128,33) = HCF(673,128) = HCF(801,673) .

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

Step 1: Since 331 > 1, we apply the division lemma to 331 and 1, to get

331 = 1 x 331 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 331 is 1

Notice that 1 = HCF(331,1) .
