HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 266, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 694, 266, 439 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, 266, 439 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, 266, 439 is 1.

HCF(694, 266, 439) = 1

Highest common factor (HCF) of 694, 266, 439 is 1.

Highest Common Factor of 694,266,439 using Euclid's algorithm

Highest Common Factor of 694,266,439 is 1

Step 1: Since 694 > 266, we apply the division lemma to 694 and 266, to get

694 = 266 x 2 + 162

Step 2: Since the reminder 266 ≠ 0, we apply division lemma to 162 and 266, to get

266 = 162 x 1 + 104

Step 3: We consider the new divisor 162 and the new remainder 104, and apply the division lemma to get

162 = 104 x 1 + 58

We consider the new divisor 104 and the new remainder 58,and apply the division lemma to get

104 = 58 x 1 + 46

We consider the new divisor 58 and the new remainder 46,and apply the division lemma to get

58 = 46 x 1 + 12

We consider the new divisor 46 and the new remainder 12,and apply the division lemma to get

46 = 12 x 3 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 694 and 266 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(46,12) = HCF(58,46) = HCF(104,58) = HCF(162,104) = HCF(266,162) = HCF(694,266) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 439 > 2, we apply the division lemma to 439 and 2, to get

439 = 2 x 219 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 439 is 1

Notice that 1 = HCF(2,1) = HCF(439,2) .
