HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7997, 1239 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7997, 1239 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 7997, 1239 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 7997, 1239 is 1.
HCF(7997, 1239) = 1
HCF of 7997, 1239 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7997, 1239 is 1.
Highest Common Factor of 7997,1239 is 1
Step 1: Since 7997 > 1239, we apply the division lemma to 7997 and 1239, to get
7997 = 1239 x 6 + 563
Step 2: Since the reminder 1239 ≠ 0, we apply division lemma to 563 and 1239, to get
1239 = 563 x 2 + 113
Step 3: We consider the new divisor 563 and the new remainder 113, and apply the division lemma to get
563 = 113 x 4 + 111
We consider the new divisor 113 and the new remainder 111,and apply the division lemma to get
113 = 111 x 1 + 2
We consider the new divisor 111 and the new remainder 2,and apply the division lemma to get
111 = 2 x 55 + 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 7997 and 1239 is 1
Notice that 1 = HCF(2,1) = HCF(111,2) = HCF(113,111) = HCF(563,113) = HCF(1239,563) = HCF(7997,1239) .
