HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 967, 205, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 967, 205, 74 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 967, 205, 74 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 967, 205, 74 is 1.

HCF(967, 205, 74) = 1

Highest common factor (HCF) of 967, 205, 74 is 1.

Highest Common Factor of 967,205,74 using Euclid's algorithm

Highest Common Factor of 967,205,74 is 1

Step 1: Since 967 > 205, we apply the division lemma to 967 and 205, to get

967 = 205 x 4 + 147

Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 147 and 205, to get

205 = 147 x 1 + 58

Step 3: We consider the new divisor 147 and the new remainder 58, and apply the division lemma to get

147 = 58 x 2 + 31

We consider the new divisor 58 and the new remainder 31,and apply the division lemma to get

58 = 31 x 1 + 27

We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get

31 = 27 x 1 + 4

We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get

27 = 4 x 6 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 967 and 205 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(58,31) = HCF(147,58) = HCF(205,147) = HCF(967,205) .

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

Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get

74 = 1 x 74 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1

Notice that 1 = HCF(74,1) .
