HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 772, 769, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 772, 769, 67 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 231, 772, 769, 67 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 231, 772, 769, 67 is 1.
HCF(231, 772, 769, 67) = 1
HCF of 231, 772, 769, 67 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 772, 769, 67 is 1.
Highest Common Factor of 231,772,769,67 is 1
Step 1: Since 772 > 231, we apply the division lemma to 772 and 231, to get
772 = 231 x 3 + 79
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 79 and 231, to get
231 = 79 x 2 + 73
Step 3: We consider the new divisor 79 and the new remainder 73, and apply the division lemma to get
79 = 73 x 1 + 6
We consider the new divisor 73 and the new remainder 6,and apply the division lemma to get
73 = 6 x 12 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 231 and 772 is 1
Notice that 1 = HCF(6,1) = HCF(73,6) = HCF(79,73) = HCF(231,79) = HCF(772,231) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get
769 = 1 x 769 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1
Notice that 1 = HCF(769,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 1, we apply the division lemma to 67 and 1, to get
67 = 1 x 67 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 67 is 1
Notice that 1 = HCF(67,1) .
