HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 317, 988 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 317, 988 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 863, 317, 988 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 863, 317, 988 is 1.
HCF(863, 317, 988) = 1
HCF of 863, 317, 988 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 317, 988 is 1.
Highest Common Factor of 863,317,988 is 1
Step 1: Since 863 > 317, we apply the division lemma to 863 and 317, to get
863 = 317 x 2 + 229
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 229 and 317, to get
317 = 229 x 1 + 88
Step 3: We consider the new divisor 229 and the new remainder 88, and apply the division lemma to get
229 = 88 x 2 + 53
We consider the new divisor 88 and the new remainder 53,and apply the division lemma to get
88 = 53 x 1 + 35
We consider the new divisor 53 and the new remainder 35,and apply the division lemma to get
53 = 35 x 1 + 18
We consider the new divisor 35 and the new remainder 18,and apply the division lemma to get
35 = 18 x 1 + 17
We consider the new divisor 18 and the new remainder 17,and apply the division lemma to get
18 = 17 x 1 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 317 is 1
Notice that 1 = HCF(17,1) = HCF(18,17) = HCF(35,18) = HCF(53,35) = HCF(88,53) = HCF(229,88) = HCF(317,229) = HCF(863,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 988 > 1, we apply the division lemma to 988 and 1, to get
988 = 1 x 988 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 988 is 1
Notice that 1 = HCF(988,1) .
