HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 54, 38, 33 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 54, 38, 33 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 54, 38, 33 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 54, 38, 33 is 1.
HCF(54, 38, 33) = 1
HCF of 54, 38, 33 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 54, 38, 33 is 1.
Highest Common Factor of 54,38,33 is 1
Step 1: Since 54 > 38, we apply the division lemma to 54 and 38, to get
54 = 38 x 1 + 16
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 16 and 38, to get
38 = 16 x 2 + 6
Step 3: We consider the new divisor 16 and the new remainder 6, and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 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 54 and 38 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(38,16) = HCF(54,38) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 33 > 2, we apply the division lemma to 33 and 2, to get
33 = 2 x 16 + 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 33 is 1
Notice that 1 = HCF(2,1) = HCF(33,2) .
