HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 36, 54, 66 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 36, 54, 66 is 6 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 36, 54, 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 36, 54, 66 is 6.
HCF(36, 54, 66) = 6
HCF of 36, 54, 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 36, 54, 66 is 6.
Highest Common Factor of 36,54,66 is 6
Step 1: Since 54 > 36, we apply the division lemma to 54 and 36, to get
54 = 36 x 1 + 18
Step 2: Since the reminder 36 ≠ 0, we apply division lemma to 18 and 36, to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 36 and 54 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 18, we apply the division lemma to 66 and 18, to get
66 = 18 x 3 + 12
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 12 and 18, to get
18 = 12 x 1 + 6
Step 3: We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 18 and 66 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(66,18) .
