HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 848, 947, 839 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 848, 947, 839 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 848, 947, 839 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 848, 947, 839 is 1.
HCF(848, 947, 839) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 848, 947, 839 is 1.
Step 1: Since 947 > 848, we apply the division lemma to 947 and 848, to get
947 = 848 x 1 + 99
Step 2: Since the reminder 848 ≠ 0, we apply division lemma to 99 and 848, to get
848 = 99 x 8 + 56
Step 3: We consider the new divisor 99 and the new remainder 56, and apply the division lemma to get
99 = 56 x 1 + 43
We consider the new divisor 56 and the new remainder 43,and apply the division lemma to get
56 = 43 x 1 + 13
We consider the new divisor 43 and the new remainder 13,and apply the division lemma to get
43 = 13 x 3 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 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 848 and 947 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(43,13) = HCF(56,43) = HCF(99,56) = HCF(848,99) = HCF(947,848) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 839 > 1, we apply the division lemma to 839 and 1, to get
839 = 1 x 839 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 839 is 1
Notice that 1 = HCF(839,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 848, 947, 839?
Answer: HCF of 848, 947, 839 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 848, 947, 839 using Euclid's Algorithm?
Answer: For arbitrary numbers 848, 947, 839 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
