HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 512, 969, 735 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 512, 969, 735 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 512, 969, 735 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 512, 969, 735 is 1.
HCF(512, 969, 735) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 512, 969, 735 is 1.
Step 1: Since 969 > 512, we apply the division lemma to 969 and 512, to get
969 = 512 x 1 + 457
Step 2: Since the reminder 512 ≠ 0, we apply division lemma to 457 and 512, to get
512 = 457 x 1 + 55
Step 3: We consider the new divisor 457 and the new remainder 55, and apply the division lemma to get
457 = 55 x 8 + 17
We consider the new divisor 55 and the new remainder 17,and apply the division lemma to get
55 = 17 x 3 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 512 and 969 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(457,55) = HCF(512,457) = HCF(969,512) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 735 > 1, we apply the division lemma to 735 and 1, to get
735 = 1 x 735 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 735 is 1
Notice that 1 = HCF(735,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 512, 969, 735?
Answer: HCF of 512, 969, 735 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 512, 969, 735 using Euclid's Algorithm?
Answer: For arbitrary numbers 512, 969, 735 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
