HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 167, 438, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 167, 438, 698 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 167, 438, 698 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 167, 438, 698 is 1.

HCF(167, 438, 698) = 1

HCF of 167, 438, 698 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 167, 438, 698 is 1.

Highest Common Factor of 167,438,698 using Euclid's algorithm

Highest Common Factor of 167,438,698 is 1

Step 1: Since 438 > 167, we apply the division lemma to 438 and 167, to get

438 = 167 x 2 + 104

Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 104 and 167, to get

167 = 104 x 1 + 63

Step 3: We consider the new divisor 104 and the new remainder 63, and apply the division lemma to get

104 = 63 x 1 + 41

We consider the new divisor 63 and the new remainder 41,and apply the division lemma to get

63 = 41 x 1 + 22

We consider the new divisor 41 and the new remainder 22,and apply the division lemma to get

41 = 22 x 1 + 19

We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get

22 = 19 x 1 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 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 167 and 438 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(41,22) = HCF(63,41) = HCF(104,63) = HCF(167,104) = HCF(438,167) .

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

Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get

698 = 1 x 698 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1

Notice that 1 = HCF(698,1) .
