HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 731, 369 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 731, 369 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 825, 731, 369 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 825, 731, 369 is 1.
HCF(825, 731, 369) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 731, 369 is 1.
Step 1: Since 825 > 731, we apply the division lemma to 825 and 731, to get
825 = 731 x 1 + 94
Step 2: Since the reminder 731 ≠ 0, we apply division lemma to 94 and 731, to get
731 = 94 x 7 + 73
Step 3: We consider the new divisor 94 and the new remainder 73, and apply the division lemma to get
94 = 73 x 1 + 21
We consider the new divisor 73 and the new remainder 21,and apply the division lemma to get
73 = 21 x 3 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 825 and 731 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(73,21) = HCF(94,73) = HCF(731,94) = HCF(825,731) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 369 > 1, we apply the division lemma to 369 and 1, to get
369 = 1 x 369 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 369 is 1
Notice that 1 = HCF(369,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 825, 731, 369?
Answer: HCF of 825, 731, 369 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 825, 731, 369 using Euclid's Algorithm?
Answer: For arbitrary numbers 825, 731, 369 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
