HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 995, 43, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 823, 995, 43, 673 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 823, 995, 43, 673 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 823, 995, 43, 673 is 1.

HCF(823, 995, 43, 673) = 1

Highest common factor (HCF) of 823, 995, 43, 673 is 1.

Highest Common Factor of 823,995,43,673 using Euclid's algorithm

Highest Common Factor of 823,995,43,673 is 1

Step 1: Since 995 > 823, we apply the division lemma to 995 and 823, to get

995 = 823 x 1 + 172

Step 2: Since the reminder 823 ≠ 0, we apply division lemma to 172 and 823, to get

823 = 172 x 4 + 135

Step 3: We consider the new divisor 172 and the new remainder 135, and apply the division lemma to get

172 = 135 x 1 + 37

We consider the new divisor 135 and the new remainder 37,and apply the division lemma to get

135 = 37 x 3 + 24

We consider the new divisor 37 and the new remainder 24,and apply the division lemma to get

37 = 24 x 1 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 823 and 995 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(37,24) = HCF(135,37) = HCF(172,135) = HCF(823,172) = HCF(995,823) .


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

Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get

43 = 1 x 43 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1

Notice that 1 = HCF(43,1) .


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

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

673 = 1 x 673 + 0

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

Notice that 1 = HCF(673,1) .
