HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 39, 68, 17, 933 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 39, 68, 17, 933 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 39, 68, 17, 933 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 39, 68, 17, 933 is 1.
HCF(39, 68, 17, 933) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 39, 68, 17, 933 is 1.
Step 1: Since 68 > 39, we apply the division lemma to 68 and 39, to get
68 = 39 x 1 + 29
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 29 and 39, to get
39 = 29 x 1 + 10
Step 3: We consider the new divisor 29 and the new remainder 10, and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 39 and 68 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(68,39) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1
Notice that 1 = HCF(17,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 933 > 1, we apply the division lemma to 933 and 1, to get
933 = 1 x 933 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 933 is 1
Notice that 1 = HCF(933,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 39, 68, 17, 933?
Answer: HCF of 39, 68, 17, 933 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 39, 68, 17, 933 using Euclid's Algorithm?
Answer: For arbitrary numbers 39, 68, 17, 933 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
