HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 316, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 316, 815 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 316, 815 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 316, 815 is 1.
HCF(316, 815) = 1
HCF of 316, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 316, 815 is 1.
Highest Common Factor of 316,815 is 1
Step 1: Since 815 > 316, we apply the division lemma to 815 and 316, to get
815 = 316 x 2 + 183
Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 183 and 316, to get
316 = 183 x 1 + 133
Step 3: We consider the new divisor 183 and the new remainder 133, and apply the division lemma to get
183 = 133 x 1 + 50
We consider the new divisor 133 and the new remainder 50,and apply the division lemma to get
133 = 50 x 2 + 33
We consider the new divisor 50 and the new remainder 33,and apply the division lemma to get
50 = 33 x 1 + 17
We consider the new divisor 33 and the new remainder 17,and apply the division lemma to get
33 = 17 x 1 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 316 and 815 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(33,17) = HCF(50,33) = HCF(133,50) = HCF(183,133) = HCF(316,183) = HCF(815,316) .
