HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 863, 807 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 285, 863, 807 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, 863, 807 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, 863, 807 is 1.

HCF(285, 863, 807) = 1

Highest common factor (HCF) of 285, 863, 807 is 1.

Highest Common Factor of 285,863,807 using Euclid's algorithm

Highest Common Factor of 285,863,807 is 1

Step 1: Since 863 > 285, we apply the division lemma to 863 and 285, to get

863 = 285 x 3 + 8

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 8 and 285, to get

285 = 8 x 35 + 5

Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get

8 = 5 x 1 + 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 285 and 863 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(285,8) = HCF(863,285) .

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

Step 1: Since 807 > 1, we apply the division lemma to 807 and 1, to get

807 = 1 x 807 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 807 is 1

Notice that 1 = HCF(807,1) .
