HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 694, 175 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 999, 694, 175 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 999, 694, 175 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 999, 694, 175 is 1.

HCF(999, 694, 175) = 1

HCF of 999, 694, 175 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 999, 694, 175 is 1.

Highest Common Factor of 999,694,175 using Euclid's algorithm

Highest Common Factor of 999,694,175 is 1

Step 1: Since 999 > 694, we apply the division lemma to 999 and 694, to get

999 = 694 x 1 + 305

Step 2: Since the reminder 694 ≠ 0, we apply division lemma to 305 and 694, to get

694 = 305 x 2 + 84

Step 3: We consider the new divisor 305 and the new remainder 84, and apply the division lemma to get

305 = 84 x 3 + 53

We consider the new divisor 84 and the new remainder 53,and apply the division lemma to get

84 = 53 x 1 + 31

We consider the new divisor 53 and the new remainder 31,and apply the division lemma to get

53 = 31 x 1 + 22

We consider the new divisor 31 and the new remainder 22,and apply the division lemma to get

31 = 22 x 1 + 9

We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get

22 = 9 x 2 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 999 and 694 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(53,31) = HCF(84,53) = HCF(305,84) = HCF(694,305) = HCF(999,694) .

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

Step 1: Since 175 > 1, we apply the division lemma to 175 and 1, to get

175 = 1 x 175 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 175 is 1

Notice that 1 = HCF(175,1) .
