HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6497, 5140, 21653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6497, 5140, 21653 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 6497, 5140, 21653 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 6497, 5140, 21653 is 1.
HCF(6497, 5140, 21653) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6497, 5140, 21653 is 1.
Step 1: Since 6497 > 5140, we apply the division lemma to 6497 and 5140, to get
6497 = 5140 x 1 + 1357
Step 2: Since the reminder 5140 ≠ 0, we apply division lemma to 1357 and 5140, to get
5140 = 1357 x 3 + 1069
Step 3: We consider the new divisor 1357 and the new remainder 1069, and apply the division lemma to get
1357 = 1069 x 1 + 288
We consider the new divisor 1069 and the new remainder 288,and apply the division lemma to get
1069 = 288 x 3 + 205
We consider the new divisor 288 and the new remainder 205,and apply the division lemma to get
288 = 205 x 1 + 83
We consider the new divisor 205 and the new remainder 83,and apply the division lemma to get
205 = 83 x 2 + 39
We consider the new divisor 83 and the new remainder 39,and apply the division lemma to get
83 = 39 x 2 + 5
We consider the new divisor 39 and the new remainder 5,and apply the division lemma to get
39 = 5 x 7 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 6497 and 5140 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(39,5) = HCF(83,39) = HCF(205,83) = HCF(288,205) = HCF(1069,288) = HCF(1357,1069) = HCF(5140,1357) = HCF(6497,5140) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21653 > 1, we apply the division lemma to 21653 and 1, to get
21653 = 1 x 21653 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21653 is 1
Notice that 1 = HCF(21653,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
