HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 452 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 172, 452 is 4 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 172, 452 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 172, 452 is 4.
HCF(172, 452) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 172, 452 is 4.
Step 1: Since 452 > 172, we apply the division lemma to 452 and 172, to get
452 = 172 x 2 + 108
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 108 and 172, to get
172 = 108 x 1 + 64
Step 3: We consider the new divisor 108 and the new remainder 64, and apply the division lemma to get
108 = 64 x 1 + 44
We consider the new divisor 64 and the new remainder 44,and apply the division lemma to get
64 = 44 x 1 + 20
We consider the new divisor 44 and the new remainder 20,and apply the division lemma to get
44 = 20 x 2 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 172 and 452 is 4
Notice that 4 = HCF(20,4) = HCF(44,20) = HCF(64,44) = HCF(108,64) = HCF(172,108) = HCF(452,172) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 172, 452?
Answer: HCF of 172, 452 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 172, 452 using Euclid's Algorithm?
Answer: For arbitrary numbers 172, 452 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
