HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 72, 39, 97, 319 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 72, 39, 97, 319 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 72, 39, 97, 319 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 72, 39, 97, 319 is 1.
HCF(72, 39, 97, 319) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 72, 39, 97, 319 is 1.
Step 1: Since 72 > 39, we apply the division lemma to 72 and 39, to get
72 = 39 x 1 + 33
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 33 and 39, to get
39 = 33 x 1 + 6
Step 3: We consider the new divisor 33 and the new remainder 6, and apply the division lemma to get
33 = 6 x 5 + 3
We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 72 and 39 is 3
Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(39,33) = HCF(72,39) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 97 > 3, we apply the division lemma to 97 and 3, to get
97 = 3 x 32 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 97 is 1
Notice that 1 = HCF(3,1) = HCF(97,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 319 > 1, we apply the division lemma to 319 and 1, to get
319 = 1 x 319 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 319 is 1
Notice that 1 = HCF(319,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 72, 39, 97, 319?
Answer: HCF of 72, 39, 97, 319 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 72, 39, 97, 319 using Euclid's Algorithm?
Answer: For arbitrary numbers 72, 39, 97, 319 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
