HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 539, 144 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 315, 539, 144 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 315, 539, 144 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 315, 539, 144 is 1.
HCF(315, 539, 144) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 315, 539, 144 is 1.
Step 1: Since 539 > 315, we apply the division lemma to 539 and 315, to get
539 = 315 x 1 + 224
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 224 and 315, to get
315 = 224 x 1 + 91
Step 3: We consider the new divisor 224 and the new remainder 91, and apply the division lemma to get
224 = 91 x 2 + 42
We consider the new divisor 91 and the new remainder 42,and apply the division lemma to get
91 = 42 x 2 + 7
We consider the new divisor 42 and the new remainder 7,and apply the division lemma to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 315 and 539 is 7
Notice that 7 = HCF(42,7) = HCF(91,42) = HCF(224,91) = HCF(315,224) = HCF(539,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 144 > 7, we apply the division lemma to 144 and 7, to get
144 = 7 x 20 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
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 7 and 144 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(144,7) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 315, 539, 144?
Answer: HCF of 315, 539, 144 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 315, 539, 144 using Euclid's Algorithm?
Answer: For arbitrary numbers 315, 539, 144 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
