HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 575, 145, 371, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 575, 145, 371, 689 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 575, 145, 371, 689 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 575, 145, 371, 689 is 1.
HCF(575, 145, 371, 689) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 575, 145, 371, 689 is 1.
Step 1: Since 575 > 145, we apply the division lemma to 575 and 145, to get
575 = 145 x 3 + 140
Step 2: Since the reminder 145 ≠ 0, we apply division lemma to 140 and 145, to get
145 = 140 x 1 + 5
Step 3: We consider the new divisor 140 and the new remainder 5, and apply the division lemma to get
140 = 5 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 575 and 145 is 5
Notice that 5 = HCF(140,5) = HCF(145,140) = HCF(575,145) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 371 > 5, we apply the division lemma to 371 and 5, to get
371 = 5 x 74 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 371 is 1
Notice that 1 = HCF(5,1) = HCF(371,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get
689 = 1 x 689 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1
Notice that 1 = HCF(689,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 575, 145, 371, 689?
Answer: HCF of 575, 145, 371, 689 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 575, 145, 371, 689 using Euclid's Algorithm?
Answer: For arbitrary numbers 575, 145, 371, 689 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
