HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 852, 1257, 2685 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 852, 1257, 2685 is 3 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 852, 1257, 2685 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 852, 1257, 2685 is 3.

HCF(852, 1257, 2685) = 3

Highest common factor (HCF) of 852, 1257, 2685 is 3.

Highest Common Factor of 852,1257,2685 using Euclid's algorithm

Highest Common Factor of 852,1257,2685 is 3

Step 1: Since 1257 > 852, we apply the division lemma to 1257 and 852, to get

1257 = 852 x 1 + 405

Step 2: Since the reminder 852 ≠ 0, we apply division lemma to 405 and 852, to get

852 = 405 x 2 + 42

Step 3: We consider the new divisor 405 and the new remainder 42, and apply the division lemma to get

405 = 42 x 9 + 27

We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get

42 = 27 x 1 + 15

We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get

27 = 15 x 1 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 852 and 1257 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(405,42) = HCF(852,405) = HCF(1257,852) .


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

Step 1: Since 2685 > 3, we apply the division lemma to 2685 and 3, to get

2685 = 3 x 895 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 2685 is 3

Notice that 3 = HCF(2685,3) .
