HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 867, 629, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 867, 629, 971 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 867, 629, 971 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 867, 629, 971 is 1.
HCF(867, 629, 971) = 1
HCF of 867, 629, 971 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 867, 629, 971 is 1.
Highest Common Factor of 867,629,971 is 1
Step 1: Since 867 > 629, we apply the division lemma to 867 and 629, to get
867 = 629 x 1 + 238
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 238 and 629, to get
629 = 238 x 2 + 153
Step 3: We consider the new divisor 238 and the new remainder 153, and apply the division lemma to get
238 = 153 x 1 + 85
We consider the new divisor 153 and the new remainder 85,and apply the division lemma to get
153 = 85 x 1 + 68
We consider the new divisor 85 and the new remainder 68,and apply the division lemma to get
85 = 68 x 1 + 17
We consider the new divisor 68 and the new remainder 17,and apply the division lemma to get
68 = 17 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 867 and 629 is 17
Notice that 17 = HCF(68,17) = HCF(85,68) = HCF(153,85) = HCF(238,153) = HCF(629,238) = HCF(867,629) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 17, we apply the division lemma to 971 and 17, to get
971 = 17 x 57 + 2
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 2 and 17, to get
17 = 2 x 8 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 971 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(971,17) .
