HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 966, 872, 397 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 966, 872, 397 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 966, 872, 397 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 966, 872, 397 is 1.
HCF(966, 872, 397) = 1
HCF of 966, 872, 397 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 966, 872, 397 is 1.
Highest Common Factor of 966,872,397 is 1
Step 1: Since 966 > 872, we apply the division lemma to 966 and 872, to get
966 = 872 x 1 + 94
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 94 and 872, to get
872 = 94 x 9 + 26
Step 3: We consider the new divisor 94 and the new remainder 26, and apply the division lemma to get
94 = 26 x 3 + 16
We consider the new divisor 26 and the new remainder 16,and apply the division lemma to get
26 = 16 x 1 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 966 and 872 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(94,26) = HCF(872,94) = HCF(966,872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 397 > 2, we apply the division lemma to 397 and 2, to get
397 = 2 x 198 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 397 is 1
Notice that 1 = HCF(2,1) = HCF(397,2) .
