HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 968, 261, 930 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 968, 261, 930 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 968, 261, 930 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 968, 261, 930 is 1.
HCF(968, 261, 930) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 968, 261, 930 is 1.
Step 1: Since 968 > 261, we apply the division lemma to 968 and 261, to get
968 = 261 x 3 + 185
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 185 and 261, to get
261 = 185 x 1 + 76
Step 3: We consider the new divisor 185 and the new remainder 76, and apply the division lemma to get
185 = 76 x 2 + 33
We consider the new divisor 76 and the new remainder 33,and apply the division lemma to get
76 = 33 x 2 + 10
We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get
33 = 10 x 3 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 968 and 261 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(76,33) = HCF(185,76) = HCF(261,185) = HCF(968,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 1, we apply the division lemma to 930 and 1, to get
930 = 1 x 930 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 930 is 1
Notice that 1 = HCF(930,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 968, 261, 930?
Answer: HCF of 968, 261, 930 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 968, 261, 930 using Euclid's Algorithm?
Answer: For arbitrary numbers 968, 261, 930 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
