HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 475, 242, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 475, 242, 13 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 673, 475, 242, 13 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 673, 475, 242, 13 is 1.
HCF(673, 475, 242, 13) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 673, 475, 242, 13 is 1.
Step 1: Since 673 > 475, we apply the division lemma to 673 and 475, to get
673 = 475 x 1 + 198
Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 198 and 475, to get
475 = 198 x 2 + 79
Step 3: We consider the new divisor 198 and the new remainder 79, and apply the division lemma to get
198 = 79 x 2 + 40
We consider the new divisor 79 and the new remainder 40,and apply the division lemma to get
79 = 40 x 1 + 39
We consider the new divisor 40 and the new remainder 39,and apply the division lemma to get
40 = 39 x 1 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 475 is 1
Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(79,40) = HCF(198,79) = HCF(475,198) = HCF(673,475) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 242 > 1, we apply the division lemma to 242 and 1, to get
242 = 1 x 242 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 242 is 1
Notice that 1 = HCF(242,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 673, 475, 242, 13?
Answer: HCF of 673, 475, 242, 13 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 673, 475, 242, 13 using Euclid's Algorithm?
