HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 34, 56, 34, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 34, 56, 34, 391 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 34, 56, 34, 391 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 34, 56, 34, 391 is 1.
HCF(34, 56, 34, 391) = 1
HCF of 34, 56, 34, 391 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 34, 56, 34, 391 is 1.
Highest Common Factor of 34,56,34,391 is 1
Step 1: Since 56 > 34, we apply the division lemma to 56 and 34, to get
56 = 34 x 1 + 22
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 22 and 34, to get
34 = 22 x 1 + 12
Step 3: We consider the new divisor 22 and the new remainder 12, and apply the division lemma to get
22 = 12 x 1 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 34 and 56 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) = HCF(56,34) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 2, we apply the division lemma to 34 and 2, to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 34 is 2
Notice that 2 = HCF(34,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 391 > 2, we apply the division lemma to 391 and 2, to get
391 = 2 x 195 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 391 is 1
Notice that 1 = HCF(2,1) = HCF(391,2) .
