HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 13, 65, 102 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 13, 65, 102 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 13, 65, 102 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 13, 65, 102 is 1.
HCF(13, 65, 102) = 1
HCF of 13, 65, 102 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 13, 65, 102 is 1.
Highest Common Factor of 13,65,102 is 1
Step 1: Since 65 > 13, we apply the division lemma to 65 and 13, to get
65 = 13 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 13 and 65 is 13
Notice that 13 = HCF(65,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 102 > 13, we apply the division lemma to 102 and 13, to get
102 = 13 x 7 + 11
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 11 and 13, to get
13 = 11 x 1 + 2
Step 3: We consider the new divisor 11 and the new remainder 2, and apply the division lemma to get
11 = 2 x 5 + 1
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 13 and 102 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(102,13) .
