HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 247 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 396, 247 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 396, 247 is 1.
HCF(396, 247) = 1
HCF of 396, 247 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 247 is 1.
Highest Common Factor of 396,247 is 1
Step 1: Since 396 > 247, we apply the division lemma to 396 and 247, to get
396 = 247 x 1 + 149
Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 149 and 247, to get
247 = 149 x 1 + 98
Step 3: We consider the new divisor 149 and the new remainder 98, and apply the division lemma to get
149 = 98 x 1 + 51
We consider the new divisor 98 and the new remainder 51,and apply the division lemma to get
98 = 51 x 1 + 47
We consider the new divisor 51 and the new remainder 47,and apply the division lemma to get
51 = 47 x 1 + 4
We consider the new divisor 47 and the new remainder 4,and apply the division lemma to get
47 = 4 x 11 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 396 and 247 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(47,4) = HCF(51,47) = HCF(98,51) = HCF(149,98) = HCF(247,149) = HCF(396,247) .
