HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 622 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 424, 622 is 2 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 424, 622 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 424, 622 is 2.
HCF(424, 622) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 424, 622 is 2.
Step 1: Since 622 > 424, we apply the division lemma to 622 and 424, to get
622 = 424 x 1 + 198
Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 198 and 424, to get
424 = 198 x 2 + 28
Step 3: We consider the new divisor 198 and the new remainder 28, and apply the division lemma to get
198 = 28 x 7 + 2
We consider the new divisor 28 and the new remainder 2, and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 424 and 622 is 2
Notice that 2 = HCF(28,2) = HCF(198,28) = HCF(424,198) = HCF(622,424) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 424, 622?
Answer: HCF of 424, 622 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 424, 622 using Euclid's Algorithm?
Answer: For arbitrary numbers 424, 622 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
