HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 65, 261, 532 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 76, 65, 261, 532 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 76, 65, 261, 532 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 76, 65, 261, 532 is 1.
HCF(76, 65, 261, 532) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 76, 65, 261, 532 is 1.
Step 1: Since 76 > 65, we apply the division lemma to 76 and 65, to get
76 = 65 x 1 + 11
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 11 and 65, to get
65 = 11 x 5 + 10
Step 3: We consider the new divisor 11 and the new remainder 10, and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 76 and 65 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(65,11) = HCF(76,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 261 > 1, we apply the division lemma to 261 and 1, to get
261 = 1 x 261 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 261 is 1
Notice that 1 = HCF(261,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 532 > 1, we apply the division lemma to 532 and 1, to get
532 = 1 x 532 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 532 is 1
Notice that 1 = HCF(532,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 76, 65, 261, 532?
Answer: HCF of 76, 65, 261, 532 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 76, 65, 261, 532 using Euclid's Algorithm?
Answer: For arbitrary numbers 76, 65, 261, 532 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
