HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 216, 179 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 216, 179 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 189, 216, 179 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 189, 216, 179 is 1.
HCF(189, 216, 179) = 1
HCF of 189, 216, 179 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 216, 179 is 1.
Highest Common Factor of 189,216,179 is 1
Step 1: Since 216 > 189, we apply the division lemma to 216 and 189, to get
216 = 189 x 1 + 27
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 27 and 189, to get
189 = 27 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 189 and 216 is 27
Notice that 27 = HCF(189,27) = HCF(216,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 179 > 27, we apply the division lemma to 179 and 27, to get
179 = 27 x 6 + 17
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 17 and 27, to get
27 = 17 x 1 + 10
Step 3: We consider the new divisor 17 and the new remainder 10, and apply the division lemma to get
17 = 10 x 1 + 7
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 27 and 179 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(179,27) .
