HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7923, 6643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7923, 6643 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 7923, 6643 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 7923, 6643 is 1.
HCF(7923, 6643) = 1
HCF of 7923, 6643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7923, 6643 is 1.
Highest Common Factor of 7923,6643 is 1
Step 1: Since 7923 > 6643, we apply the division lemma to 7923 and 6643, to get
7923 = 6643 x 1 + 1280
Step 2: Since the reminder 6643 ≠ 0, we apply division lemma to 1280 and 6643, to get
6643 = 1280 x 5 + 243
Step 3: We consider the new divisor 1280 and the new remainder 243, and apply the division lemma to get
1280 = 243 x 5 + 65
We consider the new divisor 243 and the new remainder 65,and apply the division lemma to get
243 = 65 x 3 + 48
We consider the new divisor 65 and the new remainder 48,and apply the division lemma to get
65 = 48 x 1 + 17
We consider the new divisor 48 and the new remainder 17,and apply the division lemma to get
48 = 17 x 2 + 14
We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 7923 and 6643 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(48,17) = HCF(65,48) = HCF(243,65) = HCF(1280,243) = HCF(6643,1280) = HCF(7923,6643) .
