HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 215 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 247, 215 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 247, 215 is 1.
HCF(247, 215) = 1
HCF of 247, 215 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 215 is 1.
Highest Common Factor of 247,215 is 1
Step 1: Since 247 > 215, we apply the division lemma to 247 and 215, to get
247 = 215 x 1 + 32
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 32 and 215, to get
215 = 32 x 6 + 23
Step 3: We consider the new divisor 32 and the new remainder 23, and apply the division lemma to get
32 = 23 x 1 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 247 and 215 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(215,32) = HCF(247,215) .
