HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 996 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 397, 996 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 397, 996 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 397, 996 is 1.
HCF(397, 996) = 1
HCF of 397, 996 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 397, 996 is 1.
Highest Common Factor of 397,996 is 1
Step 1: Since 996 > 397, we apply the division lemma to 996 and 397, to get
996 = 397 x 2 + 202
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 202 and 397, to get
397 = 202 x 1 + 195
Step 3: We consider the new divisor 202 and the new remainder 195, and apply the division lemma to get
202 = 195 x 1 + 7
We consider the new divisor 195 and the new remainder 7,and apply the division lemma to get
195 = 7 x 27 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 996 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(195,7) = HCF(202,195) = HCF(397,202) = HCF(996,397) .
