HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9474, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9474, 689 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 9474, 689 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 9474, 689 is 1.
HCF(9474, 689) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9474, 689 is 1.
Step 1: Since 9474 > 689, we apply the division lemma to 9474 and 689, to get
9474 = 689 x 13 + 517
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 517 and 689, to get
689 = 517 x 1 + 172
Step 3: We consider the new divisor 517 and the new remainder 172, and apply the division lemma to get
517 = 172 x 3 + 1
We consider the new divisor 172 and the new remainder 1, and apply the division lemma to get
172 = 1 x 172 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9474 and 689 is 1
Notice that 1 = HCF(172,1) = HCF(517,172) = HCF(689,517) = HCF(9474,689) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 9474, 689?
Answer: HCF of 9474, 689 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 9474, 689 using Euclid's Algorithm?
Answer: For arbitrary numbers 9474, 689 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
