HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 86, 38, 321 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 86, 38, 321 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 56, 86, 38, 321 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 56, 86, 38, 321 is 1.
HCF(56, 86, 38, 321) = 1
HCF of 56, 86, 38, 321 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 56, 86, 38, 321 is 1.
Highest Common Factor of 56,86,38,321 is 1
Step 1: Since 86 > 56, we apply the division lemma to 86 and 56, to get
86 = 56 x 1 + 30
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 30 and 56, to get
56 = 30 x 1 + 26
Step 3: We consider the new divisor 30 and the new remainder 26, and apply the division lemma to get
30 = 26 x 1 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 56 and 86 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(56,30) = HCF(86,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 2, we apply the division lemma to 38 and 2, to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 38 is 2
Notice that 2 = HCF(38,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 321 > 2, we apply the division lemma to 321 and 2, to get
321 = 2 x 160 + 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 321 is 1
Notice that 1 = HCF(2,1) = HCF(321,2) .
