HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 13, 16, 66, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 13, 16, 66, 74 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, 16, 66, 74 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, 16, 66, 74 is 1.
HCF(13, 16, 66, 74) = 1
HCF of 13, 16, 66, 74 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, 16, 66, 74 is 1.
Highest Common Factor of 13,16,66,74 is 1
Step 1: Since 16 > 13, we apply the division lemma to 16 and 13, to get
16 = 13 x 1 + 3
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 3 and 13, to get
13 = 3 x 4 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 16 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get
66 = 1 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1
Notice that 1 = HCF(66,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get
74 = 1 x 74 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1
Notice that 1 = HCF(74,1) .
