HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 969, 711, 399 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 969, 711, 399 is 3 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 969, 711, 399 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 969, 711, 399 is 3.
HCF(969, 711, 399) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 969, 711, 399 is 3.
Step 1: Since 969 > 711, we apply the division lemma to 969 and 711, to get
969 = 711 x 1 + 258
Step 2: Since the reminder 711 ≠ 0, we apply division lemma to 258 and 711, to get
711 = 258 x 2 + 195
Step 3: We consider the new divisor 258 and the new remainder 195, and apply the division lemma to get
258 = 195 x 1 + 63
We consider the new divisor 195 and the new remainder 63,and apply the division lemma to get
195 = 63 x 3 + 6
We consider the new divisor 63 and the new remainder 6,and apply the division lemma to get
63 = 6 x 10 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 969 and 711 is 3
Notice that 3 = HCF(6,3) = HCF(63,6) = HCF(195,63) = HCF(258,195) = HCF(711,258) = HCF(969,711) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 399 > 3, we apply the division lemma to 399 and 3, to get
399 = 3 x 133 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 399 is 3
Notice that 3 = HCF(399,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
