HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 60, 69, 11 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 12, 60, 69, 11 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 12, 60, 69, 11 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 12, 60, 69, 11 is 1.
HCF(12, 60, 69, 11) = 1
HCF of 12, 60, 69, 11 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 12, 60, 69, 11 is 1.
Highest Common Factor of 12,60,69,11 is 1
Step 1: Since 60 > 12, we apply the division lemma to 60 and 12, to get
60 = 12 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 60 is 12
Notice that 12 = HCF(60,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 12, we apply the division lemma to 69 and 12, to get
69 = 12 x 5 + 9
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 9 and 12, to get
12 = 9 x 1 + 3
Step 3: We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 69 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(69,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 11 > 3, we apply the division lemma to 11 and 3, to get
11 = 3 x 3 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 11 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) .
