HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 935, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 691, 935, 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 691, 935, 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 691, 935, 67 is 1.
HCF(691, 935, 67) = 1
HCF of 691, 935, 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 691, 935, 67 is 1.
Highest Common Factor of 691,935,67 is 1
Step 1: Since 935 > 691, we apply the division lemma to 935 and 691, to get
935 = 691 x 1 + 244
Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 244 and 691, to get
691 = 244 x 2 + 203
Step 3: We consider the new divisor 244 and the new remainder 203, and apply the division lemma to get
244 = 203 x 1 + 41
We consider the new divisor 203 and the new remainder 41,and apply the division lemma to get
203 = 41 x 4 + 39
We consider the new divisor 41 and the new remainder 39,and apply the division lemma to get
41 = 39 x 1 + 2
We consider the new divisor 39 and the new remainder 2,and apply the division lemma to get
39 = 2 x 19 + 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 691 and 935 is 1
Notice that 1 = HCF(2,1) = HCF(39,2) = HCF(41,39) = HCF(203,41) = HCF(244,203) = HCF(691,244) = HCF(935,691) .
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) .
