HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 3681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 3681 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 779, 3681 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 779, 3681 is 1.
HCF(779, 3681) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 3681 is 1.
Step 1: Since 3681 > 779, we apply the division lemma to 3681 and 779, to get
3681 = 779 x 4 + 565
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 565 and 779, to get
779 = 565 x 1 + 214
Step 3: We consider the new divisor 565 and the new remainder 214, and apply the division lemma to get
565 = 214 x 2 + 137
We consider the new divisor 214 and the new remainder 137,and apply the division lemma to get
214 = 137 x 1 + 77
We consider the new divisor 137 and the new remainder 77,and apply the division lemma to get
137 = 77 x 1 + 60
We consider the new divisor 77 and the new remainder 60,and apply the division lemma to get
77 = 60 x 1 + 17
We consider the new divisor 60 and the new remainder 17,and apply the division lemma to get
60 = 17 x 3 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 3681 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(60,17) = HCF(77,60) = HCF(137,77) = HCF(214,137) = HCF(565,214) = HCF(779,565) = HCF(3681,779) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 779, 3681?
Answer: HCF of 779, 3681 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 779, 3681 using Euclid's Algorithm?
Answer: For arbitrary numbers 779, 3681 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
