HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 66, 13, 538 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 66, 13, 538 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 66, 13, 538 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 66, 13, 538 is 1.
HCF(66, 13, 538) = 1
HCF of 66, 13, 538 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 66, 13, 538 is 1.
Highest Common Factor of 66,13,538 is 1
Step 1: Since 66 > 13, we apply the division lemma to 66 and 13, to get
66 = 13 x 5 + 1
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 1 and 13, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 66 and 13 is 1
Notice that 1 = HCF(13,1) = HCF(66,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 1, we apply the division lemma to 538 and 1, to get
538 = 1 x 538 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 538 is 1
Notice that 1 = HCF(538,1) .
