HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 215, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 215, 847 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 215, 847 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 215, 847 is 1.
HCF(215, 847) = 1
HCF of 215, 847 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 215, 847 is 1.
Highest Common Factor of 215,847 is 1
Step 1: Since 847 > 215, we apply the division lemma to 847 and 215, to get
847 = 215 x 3 + 202
Step 2: Since the reminder 215 ≠ 0, we apply division lemma to 202 and 215, to get
215 = 202 x 1 + 13
Step 3: We consider the new divisor 202 and the new remainder 13, and apply the division lemma to get
202 = 13 x 15 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 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 215 and 847 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(202,13) = HCF(215,202) = HCF(847,215) .
