HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 694, 425 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 694, 425 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 694, 425 is 1.
HCF(694, 425) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 694, 425 is 1.
Step 1: Since 694 > 425, we apply the division lemma to 694 and 425, to get
694 = 425 x 1 + 269
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 269 and 425, to get
425 = 269 x 1 + 156
Step 3: We consider the new divisor 269 and the new remainder 156, and apply the division lemma to get
269 = 156 x 1 + 113
We consider the new divisor 156 and the new remainder 113,and apply the division lemma to get
156 = 113 x 1 + 43
We consider the new divisor 113 and the new remainder 43,and apply the division lemma to get
113 = 43 x 2 + 27
We consider the new divisor 43 and the new remainder 27,and apply the division lemma to get
43 = 27 x 1 + 16
We consider the new divisor 27 and the new remainder 16,and apply the division lemma to get
27 = 16 x 1 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma 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 694 and 425 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(43,27) = HCF(113,43) = HCF(156,113) = HCF(269,156) = HCF(425,269) = HCF(694,425) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 694, 425?
Answer: HCF of 694, 425 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 694, 425 using Euclid's Algorithm?
Answer: For arbitrary numbers 694, 425 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
