HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 443, 832, 38 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 443, 832, 38 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 443, 832, 38 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 443, 832, 38 is 1.
HCF(443, 832, 38) = 1
HCF of 443, 832, 38 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 443, 832, 38 is 1.
Highest Common Factor of 443,832,38 is 1
Step 1: Since 832 > 443, we apply the division lemma to 832 and 443, to get
832 = 443 x 1 + 389
Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 389 and 443, to get
443 = 389 x 1 + 54
Step 3: We consider the new divisor 389 and the new remainder 54, and apply the division lemma to get
389 = 54 x 7 + 11
We consider the new divisor 54 and the new remainder 11,and apply the division lemma to get
54 = 11 x 4 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 443 and 832 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(54,11) = HCF(389,54) = HCF(443,389) = HCF(832,443) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 1, we apply the division lemma to 38 and 1, to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 38 is 1
Notice that 1 = HCF(38,1) .
