HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7243, 9965 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7243, 9965 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 7243, 9965 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 7243, 9965 is 1.
HCF(7243, 9965) = 1
HCF of 7243, 9965 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7243, 9965 is 1.
Highest Common Factor of 7243,9965 is 1
Step 1: Since 9965 > 7243, we apply the division lemma to 9965 and 7243, to get
9965 = 7243 x 1 + 2722
Step 2: Since the reminder 7243 ≠ 0, we apply division lemma to 2722 and 7243, to get
7243 = 2722 x 2 + 1799
Step 3: We consider the new divisor 2722 and the new remainder 1799, and apply the division lemma to get
2722 = 1799 x 1 + 923
We consider the new divisor 1799 and the new remainder 923,and apply the division lemma to get
1799 = 923 x 1 + 876
We consider the new divisor 923 and the new remainder 876,and apply the division lemma to get
923 = 876 x 1 + 47
We consider the new divisor 876 and the new remainder 47,and apply the division lemma to get
876 = 47 x 18 + 30
We consider the new divisor 47 and the new remainder 30,and apply the division lemma to get
47 = 30 x 1 + 17
We consider the new divisor 30 and the new remainder 17,and apply the division lemma to get
30 = 17 x 1 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 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 7243 and 9965 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(30,17) = HCF(47,30) = HCF(876,47) = HCF(923,876) = HCF(1799,923) = HCF(2722,1799) = HCF(7243,2722) = HCF(9965,7243) .
