HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 575, 93 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 979, 575, 93 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 979, 575, 93 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 979, 575, 93 is 1.
HCF(979, 575, 93) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 979, 575, 93 is 1.
Step 1: Since 979 > 575, we apply the division lemma to 979 and 575, to get
979 = 575 x 1 + 404
Step 2: Since the reminder 575 ≠ 0, we apply division lemma to 404 and 575, to get
575 = 404 x 1 + 171
Step 3: We consider the new divisor 404 and the new remainder 171, and apply the division lemma to get
404 = 171 x 2 + 62
We consider the new divisor 171 and the new remainder 62,and apply the division lemma to get
171 = 62 x 2 + 47
We consider the new divisor 62 and the new remainder 47,and apply the division lemma to get
62 = 47 x 1 + 15
We consider the new divisor 47 and the new remainder 15,and apply the division lemma to get
47 = 15 x 3 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 979 and 575 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(47,15) = HCF(62,47) = HCF(171,62) = HCF(404,171) = HCF(575,404) = HCF(979,575) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 93 > 1, we apply the division lemma to 93 and 1, to get
93 = 1 x 93 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 93 is 1
Notice that 1 = HCF(93,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 979, 575, 93?
Answer: HCF of 979, 575, 93 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 979, 575, 93 using Euclid's Algorithm?
Answer: For arbitrary numbers 979, 575, 93 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
