HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 1551, 5971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 285, 1551, 5971 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 285, 1551, 5971 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 285, 1551, 5971 is 1.

HCF(285, 1551, 5971) = 1

Highest common factor (HCF) of 285, 1551, 5971 is 1.

Highest Common Factor of 285,1551,5971 using Euclid's algorithm

Highest Common Factor of 285,1551,5971 is 1

Step 1: Since 1551 > 285, we apply the division lemma to 1551 and 285, to get

1551 = 285 x 5 + 126

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 126 and 285, to get

285 = 126 x 2 + 33

Step 3: We consider the new divisor 126 and the new remainder 33, and apply the division lemma to get

126 = 33 x 3 + 27

We consider the new divisor 33 and the new remainder 27,and apply the division lemma to get

33 = 27 x 1 + 6

We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get

27 = 6 x 4 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 285 and 1551 is 3

Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(33,27) = HCF(126,33) = HCF(285,126) = HCF(1551,285) .


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

Step 1: Since 5971 > 3, we apply the division lemma to 5971 and 3, to get

5971 = 3 x 1990 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 5971 is 1

Notice that 1 = HCF(3,1) = HCF(5971,3) .
