HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 97, 445, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 97, 445, 167 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 97, 445, 167 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 97, 445, 167 is 1.

HCF(97, 445, 167) = 1

Highest common factor (HCF) of 97, 445, 167 is 1.

Highest Common Factor of 97,445,167 using Euclid's algorithm

Highest Common Factor of 97,445,167 is 1

Step 1: Since 445 > 97, we apply the division lemma to 445 and 97, to get

445 = 97 x 4 + 57

Step 2: Since the reminder 97 ≠ 0, we apply division lemma to 57 and 97, to get

97 = 57 x 1 + 40

Step 3: We consider the new divisor 57 and the new remainder 40, and apply the division lemma to get

57 = 40 x 1 + 17

We consider the new divisor 40 and the new remainder 17,and apply the division lemma to get

40 = 17 x 2 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 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 97 and 445 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(40,17) = HCF(57,40) = HCF(97,57) = HCF(445,97) .

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

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

167 = 1 x 167 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1

Notice that 1 = HCF(167,1) .
