HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 932, 515, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 932, 515, 70 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 932, 515, 70 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 932, 515, 70 is 1.
HCF(932, 515, 70) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 932, 515, 70 is 1.
Step 1: Since 932 > 515, we apply the division lemma to 932 and 515, to get
932 = 515 x 1 + 417
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 417 and 515, to get
515 = 417 x 1 + 98
Step 3: We consider the new divisor 417 and the new remainder 98, and apply the division lemma to get
417 = 98 x 4 + 25
We consider the new divisor 98 and the new remainder 25,and apply the division lemma to get
98 = 25 x 3 + 23
We consider the new divisor 25 and the new remainder 23,and apply the division lemma to get
25 = 23 x 1 + 2
We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get
23 = 2 x 11 + 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 932 and 515 is 1
Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(25,23) = HCF(98,25) = HCF(417,98) = HCF(515,417) = HCF(932,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1
Notice that 1 = HCF(70,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 932, 515, 70?
Answer: HCF of 932, 515, 70 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 932, 515, 70 using Euclid's Algorithm?
Answer: For arbitrary numbers 932, 515, 70 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
