HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7043, 6872, 68696 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7043, 6872, 68696 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 7043, 6872, 68696 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 7043, 6872, 68696 is 1.
HCF(7043, 6872, 68696) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7043, 6872, 68696 is 1.
Step 1: Since 7043 > 6872, we apply the division lemma to 7043 and 6872, to get
7043 = 6872 x 1 + 171
Step 2: Since the reminder 6872 ≠ 0, we apply division lemma to 171 and 6872, to get
6872 = 171 x 40 + 32
Step 3: We consider the new divisor 171 and the new remainder 32, and apply the division lemma to get
171 = 32 x 5 + 11
We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get
32 = 11 x 2 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7043 and 6872 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(171,32) = HCF(6872,171) = HCF(7043,6872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 68696 > 1, we apply the division lemma to 68696 and 1, to get
68696 = 1 x 68696 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 68696 is 1
Notice that 1 = HCF(68696,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
