HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 646, 614 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 646, 614 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 975, 646, 614 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 975, 646, 614 is 1.
HCF(975, 646, 614) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 646, 614 is 1.
Step 1: Since 975 > 646, we apply the division lemma to 975 and 646, to get
975 = 646 x 1 + 329
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 329 and 646, to get
646 = 329 x 1 + 317
Step 3: We consider the new divisor 329 and the new remainder 317, and apply the division lemma to get
329 = 317 x 1 + 12
We consider the new divisor 317 and the new remainder 12,and apply the division lemma to get
317 = 12 x 26 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 975 and 646 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(317,12) = HCF(329,317) = HCF(646,329) = HCF(975,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 614 > 1, we apply the division lemma to 614 and 1, to get
614 = 1 x 614 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 614 is 1
Notice that 1 = HCF(614,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 975, 646, 614?
Answer: HCF of 975, 646, 614 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 975, 646, 614 using Euclid's Algorithm?
Answer: For arbitrary numbers 975, 646, 614 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
