HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 169, 208 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 169, 208 is 13 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 676, 169, 208 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 676, 169, 208 is 13.
HCF(676, 169, 208) = 13
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 169, 208 is 13.
Step 1: Since 676 > 169, we apply the division lemma to 676 and 169, to get
676 = 169 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 169, the HCF of 676 and 169 is 169
Notice that 169 = HCF(676,169) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 208 > 169, we apply the division lemma to 208 and 169, to get
208 = 169 x 1 + 39
Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 39 and 169, to get
169 = 39 x 4 + 13
Step 3: We consider the new divisor 39 and the new remainder 13, and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 169 and 208 is 13
Notice that 13 = HCF(39,13) = HCF(169,39) = HCF(208,169) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 676, 169, 208?
Answer: HCF of 676, 169, 208 is 13 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 676, 169, 208 using Euclid's Algorithm?
Answer: For arbitrary numbers 676, 169, 208 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
