HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 978 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 978 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 268, 978 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 268, 978 is 2.
HCF(268, 978) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 268, 978 is 2.
Step 1: Since 978 > 268, we apply the division lemma to 978 and 268, to get
978 = 268 x 3 + 174
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 174 and 268, to get
268 = 174 x 1 + 94
Step 3: We consider the new divisor 174 and the new remainder 94, and apply the division lemma to get
174 = 94 x 1 + 80
We consider the new divisor 94 and the new remainder 80,and apply the division lemma to get
94 = 80 x 1 + 14
We consider the new divisor 80 and the new remainder 14,and apply the division lemma to get
80 = 14 x 5 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 268 and 978 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(80,14) = HCF(94,80) = HCF(174,94) = HCF(268,174) = HCF(978,268) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 268, 978?
Answer: HCF of 268, 978 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 268, 978 using Euclid's Algorithm?
Answer: For arbitrary numbers 268, 978 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
