HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 961, 964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 209, 961, 964 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 209, 961, 964 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 209, 961, 964 is 1.
HCF(209, 961, 964) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 209, 961, 964 is 1.
Step 1: Since 961 > 209, we apply the division lemma to 961 and 209, to get
961 = 209 x 4 + 125
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 125 and 209, to get
209 = 125 x 1 + 84
Step 3: We consider the new divisor 125 and the new remainder 84, and apply the division lemma to get
125 = 84 x 1 + 41
We consider the new divisor 84 and the new remainder 41,and apply the division lemma to get
84 = 41 x 2 + 2
We consider the new divisor 41 and the new remainder 2,and apply the division lemma to get
41 = 2 x 20 + 1
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 209 and 961 is 1
Notice that 1 = HCF(2,1) = HCF(41,2) = HCF(84,41) = HCF(125,84) = HCF(209,125) = HCF(961,209) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 964 > 1, we apply the division lemma to 964 and 1, to get
964 = 1 x 964 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 964 is 1
Notice that 1 = HCF(964,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
