HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 216 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 216 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 797, 216 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 797, 216 is 1.
HCF(797, 216) = 1
HCF of 797, 216 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 216 is 1.
Highest Common Factor of 797,216 is 1
Step 1: Since 797 > 216, we apply the division lemma to 797 and 216, to get
797 = 216 x 3 + 149
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 149 and 216, to get
216 = 149 x 1 + 67
Step 3: We consider the new divisor 149 and the new remainder 67, and apply the division lemma to get
149 = 67 x 2 + 15
We consider the new divisor 67 and the new remainder 15,and apply the division lemma to get
67 = 15 x 4 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 216 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(67,15) = HCF(149,67) = HCF(216,149) = HCF(797,216) .
