HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2495, 1221, 21883 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2495, 1221, 21883 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 2495, 1221, 21883 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 2495, 1221, 21883 is 1.
HCF(2495, 1221, 21883) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2495, 1221, 21883 is 1.
Step 1: Since 2495 > 1221, we apply the division lemma to 2495 and 1221, to get
2495 = 1221 x 2 + 53
Step 2: Since the reminder 1221 ≠ 0, we apply division lemma to 53 and 1221, to get
1221 = 53 x 23 + 2
Step 3: We consider the new divisor 53 and the new remainder 2, and apply the division lemma to get
53 = 2 x 26 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2495 and 1221 is 1
Notice that 1 = HCF(2,1) = HCF(53,2) = HCF(1221,53) = HCF(2495,1221) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21883 > 1, we apply the division lemma to 21883 and 1, to get
21883 = 1 x 21883 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21883 is 1
Notice that 1 = HCF(21883,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 2495, 1221, 21883?
Answer: HCF of 2495, 1221, 21883 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 2495, 1221, 21883 using Euclid's Algorithm?
Answer: For arbitrary numbers 2495, 1221, 21883 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
