HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 979 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 209, 979 is 11 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 209, 979 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 209, 979 is 11.
HCF(209, 979) = 11
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 209, 979 is 11.
Step 1: Since 979 > 209, we apply the division lemma to 979 and 209, to get
979 = 209 x 4 + 143
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 143 and 209, to get
209 = 143 x 1 + 66
Step 3: We consider the new divisor 143 and the new remainder 66, and apply the division lemma to get
143 = 66 x 2 + 11
We consider the new divisor 66 and the new remainder 11, and apply the division lemma to get
66 = 11 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 209 and 979 is 11
Notice that 11 = HCF(66,11) = HCF(143,66) = HCF(209,143) = HCF(979,209) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 209, 979?
Answer: HCF of 209, 979 is 11 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 209, 979 using Euclid's Algorithm?
Answer: For arbitrary numbers 209, 979 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
