HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 895, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 895, 694 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 657, 895, 694 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 657, 895, 694 is 1.
HCF(657, 895, 694) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 895, 694 is 1.
Step 1: Since 895 > 657, we apply the division lemma to 895 and 657, to get
895 = 657 x 1 + 238
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 238 and 657, to get
657 = 238 x 2 + 181
Step 3: We consider the new divisor 238 and the new remainder 181, and apply the division lemma to get
238 = 181 x 1 + 57
We consider the new divisor 181 and the new remainder 57,and apply the division lemma to get
181 = 57 x 3 + 10
We consider the new divisor 57 and the new remainder 10,and apply the division lemma to get
57 = 10 x 5 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 657 and 895 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(57,10) = HCF(181,57) = HCF(238,181) = HCF(657,238) = HCF(895,657) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get
694 = 1 x 694 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1
Notice that 1 = HCF(694,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 657, 895, 694?
Answer: HCF of 657, 895, 694 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 657, 895, 694 using Euclid's Algorithm?
Answer: For arbitrary numbers 657, 895, 694 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
