HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 772, 7864, 7117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 772, 7864, 7117 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 772, 7864, 7117 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 772, 7864, 7117 is 1.
HCF(772, 7864, 7117) = 1
HCF of 772, 7864, 7117 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 772, 7864, 7117 is 1.
Highest Common Factor of 772,7864,7117 is 1
Step 1: Since 7864 > 772, we apply the division lemma to 7864 and 772, to get
7864 = 772 x 10 + 144
Step 2: Since the reminder 772 ≠ 0, we apply division lemma to 144 and 772, to get
772 = 144 x 5 + 52
Step 3: We consider the new divisor 144 and the new remainder 52, and apply the division lemma to get
144 = 52 x 2 + 40
We consider the new divisor 52 and the new remainder 40,and apply the division lemma to get
52 = 40 x 1 + 12
We consider the new divisor 40 and the new remainder 12,and apply the division lemma to get
40 = 12 x 3 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 772 and 7864 is 4
Notice that 4 = HCF(12,4) = HCF(40,12) = HCF(52,40) = HCF(144,52) = HCF(772,144) = HCF(7864,772) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7117 > 4, we apply the division lemma to 7117 and 4, to get
7117 = 4 x 1779 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 7117 is 1
Notice that 1 = HCF(4,1) = HCF(7117,4) .
