HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 111, 66 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 111, 66 is 3 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 180, 111, 66 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 180, 111, 66 is 3.
HCF(180, 111, 66) = 3
HCF of 180, 111, 66 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 111, 66 is 3.
Highest Common Factor of 180,111,66 is 3
Step 1: Since 180 > 111, we apply the division lemma to 180 and 111, to get
180 = 111 x 1 + 69
Step 2: Since the reminder 111 ≠ 0, we apply division lemma to 69 and 111, to get
111 = 69 x 1 + 42
Step 3: We consider the new divisor 69 and the new remainder 42, and apply the division lemma to get
69 = 42 x 1 + 27
We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 180 and 111 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(69,42) = HCF(111,69) = HCF(180,111) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 3, we apply the division lemma to 66 and 3, to get
66 = 3 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 66 is 3
Notice that 3 = HCF(66,3) .
