HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 967 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 287, 967 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 287, 967 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 287, 967 is 1.

HCF(287, 967) = 1

Highest common factor (HCF) of 287, 967 is 1.

Highest Common Factor of 287,967 using Euclid's algorithm

Highest Common Factor of 287,967 is 1

Step 1: Since 967 > 287, we apply the division lemma to 967 and 287, to get

967 = 287 x 3 + 106

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 106 and 287, to get

287 = 106 x 2 + 75

Step 3: We consider the new divisor 106 and the new remainder 75, and apply the division lemma to get

106 = 75 x 1 + 31

We consider the new divisor 75 and the new remainder 31,and apply the division lemma to get

75 = 31 x 2 + 13

We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get

31 = 13 x 2 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 287 and 967 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(75,31) = HCF(106,75) = HCF(287,106) = HCF(967,287) .
