HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 809, 996, 440, 699 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 809, 996, 440, 699 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 809, 996, 440, 699 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 809, 996, 440, 699 is 1.
HCF(809, 996, 440, 699) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 809, 996, 440, 699 is 1.
Step 1: Since 996 > 809, we apply the division lemma to 996 and 809, to get
996 = 809 x 1 + 187
Step 2: Since the reminder 809 ≠ 0, we apply division lemma to 187 and 809, to get
809 = 187 x 4 + 61
Step 3: We consider the new divisor 187 and the new remainder 61, and apply the division lemma to get
187 = 61 x 3 + 4
We consider the new divisor 61 and the new remainder 4,and apply the division lemma to get
61 = 4 x 15 + 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 809 and 996 is 1
Notice that 1 = HCF(4,1) = HCF(61,4) = HCF(187,61) = HCF(809,187) = HCF(996,809) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 440 > 1, we apply the division lemma to 440 and 1, to get
440 = 1 x 440 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 440 is 1
Notice that 1 = HCF(440,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 1, we apply the division lemma to 699 and 1, to get
699 = 1 x 699 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 699 is 1
Notice that 1 = HCF(699,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 809, 996, 440, 699?
Answer: HCF of 809, 996, 440, 699 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 809, 996, 440, 699 using Euclid's Algorithm?
Answer: For arbitrary numbers 809, 996, 440, 699 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
