HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 51, 68, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 51, 68, 27 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 51, 68, 27 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 51, 68, 27 is 1.
HCF(51, 68, 27) = 1
HCF of 51, 68, 27 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 51, 68, 27 is 1.
Highest Common Factor of 51,68,27 is 1
Step 1: Since 68 > 51, we apply the division lemma to 68 and 51, to get
68 = 51 x 1 + 17
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 17 and 51, to get
51 = 17 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 51 and 68 is 17
Notice that 17 = HCF(51,17) = HCF(68,51) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 27 > 17, we apply the division lemma to 27 and 17, to get
27 = 17 x 1 + 10
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 10 and 17, to get
17 = 10 x 1 + 7
Step 3: We consider the new divisor 10 and the new remainder 7, and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 27 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) .
