HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 969, 272 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 969, 272 is 17 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 969, 272 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 969, 272 is 17.
HCF(969, 272) = 17
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 969, 272 is 17.
Step 1: Since 969 > 272, we apply the division lemma to 969 and 272, to get
969 = 272 x 3 + 153
Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 153 and 272, to get
272 = 153 x 1 + 119
Step 3: We consider the new divisor 153 and the new remainder 119, and apply the division lemma to get
153 = 119 x 1 + 34
We consider the new divisor 119 and the new remainder 34,and apply the division lemma to get
119 = 34 x 3 + 17
We consider the new divisor 34 and the new remainder 17,and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 969 and 272 is 17
Notice that 17 = HCF(34,17) = HCF(119,34) = HCF(153,119) = HCF(272,153) = HCF(969,272) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 969, 272?
Answer: HCF of 969, 272 is 17 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 969, 272 using Euclid's Algorithm?
Answer: For arbitrary numbers 969, 272 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
