HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 227, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 631, 227, 969 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 631, 227, 969 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 631, 227, 969 is 1.

HCF(631, 227, 969) = 1

Highest common factor (HCF) of 631, 227, 969 is 1.

Highest Common Factor of 631,227,969 using Euclid's algorithm

Highest Common Factor of 631,227,969 is 1

Step 1: Since 631 > 227, we apply the division lemma to 631 and 227, to get

631 = 227 x 2 + 177

Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 177 and 227, to get

227 = 177 x 1 + 50

Step 3: We consider the new divisor 177 and the new remainder 50, and apply the division lemma to get

177 = 50 x 3 + 27

We consider the new divisor 50 and the new remainder 27,and apply the division lemma to get

50 = 27 x 1 + 23

We consider the new divisor 27 and the new remainder 23,and apply the division lemma to get

27 = 23 x 1 + 4

We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get

23 = 4 x 5 + 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 631 and 227 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(27,23) = HCF(50,27) = HCF(177,50) = HCF(227,177) = HCF(631,227) .

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

Step 1: Since 969 > 1, we apply the division lemma to 969 and 1, to get

969 = 1 x 969 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 969 is 1

Notice that 1 = HCF(969,1) .
