HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 694, 844 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 429, 694, 844 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 429, 694, 844 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 429, 694, 844 is 1.

HCF(429, 694, 844) = 1

Highest Common Factor of 429,694,844 using Euclid's algorithm

Highest Common Factor of 429,694,844 is 1

Step 1: Since 694 > 429, we apply the division lemma to 694 and 429, to get

694 = 429 x 1 + 265

Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 265 and 429, to get

429 = 265 x 1 + 164

Step 3: We consider the new divisor 265 and the new remainder 164, and apply the division lemma to get

265 = 164 x 1 + 101

We consider the new divisor 164 and the new remainder 101,and apply the division lemma to get

164 = 101 x 1 + 63

We consider the new divisor 101 and the new remainder 63,and apply the division lemma to get

101 = 63 x 1 + 38

We consider the new divisor 63 and the new remainder 38,and apply the division lemma to get

63 = 38 x 1 + 25

We consider the new divisor 38 and the new remainder 25,and apply the division lemma to get

38 = 25 x 1 + 13

We consider the new divisor 25 and the new remainder 13,and apply the division lemma to get

25 = 13 x 1 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 429 and 694 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(38,25) = HCF(63,38) = HCF(101,63) = HCF(164,101) = HCF(265,164) = HCF(429,265) = HCF(694,429) .

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

Step 1: Since 844 > 1, we apply the division lemma to 844 and 1, to get

844 = 1 x 844 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 844 is 1

Notice that 1 = HCF(844,1) .
