HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 375, 37 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 375, 37 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 531, 375, 37 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 531, 375, 37 is 1.
HCF(531, 375, 37) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 375, 37 is 1.
Step 1: Since 531 > 375, we apply the division lemma to 531 and 375, to get
531 = 375 x 1 + 156
Step 2: Since the reminder 375 ≠ 0, we apply division lemma to 156 and 375, to get
375 = 156 x 2 + 63
Step 3: We consider the new divisor 156 and the new remainder 63, and apply the division lemma to get
156 = 63 x 2 + 30
We consider the new divisor 63 and the new remainder 30,and apply the division lemma to get
63 = 30 x 2 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 531 and 375 is 3
Notice that 3 = HCF(30,3) = HCF(63,30) = HCF(156,63) = HCF(375,156) = HCF(531,375) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 37 > 3, we apply the division lemma to 37 and 3, to get
37 = 3 x 12 + 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 37 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 531, 375, 37?
Answer: HCF of 531, 375, 37 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 531, 375, 37 using Euclid's Algorithm?
Answer: For arbitrary numbers 531, 375, 37 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
