HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 316, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 856, 316, 987 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 856, 316, 987 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 856, 316, 987 is 1.

HCF(856, 316, 987) = 1

Highest common factor (HCF) of 856, 316, 987 is 1.

Highest Common Factor of 856,316,987 using Euclid's algorithm

Highest Common Factor of 856,316,987 is 1

Step 1: Since 856 > 316, we apply the division lemma to 856 and 316, to get

856 = 316 x 2 + 224

Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 224 and 316, to get

316 = 224 x 1 + 92

Step 3: We consider the new divisor 224 and the new remainder 92, and apply the division lemma to get

224 = 92 x 2 + 40

We consider the new divisor 92 and the new remainder 40,and apply the division lemma to get

92 = 40 x 2 + 12

We consider the new divisor 40 and the new remainder 12,and apply the division lemma to get

40 = 12 x 3 + 4

We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get

12 = 4 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 856 and 316 is 4

Notice that 4 = HCF(12,4) = HCF(40,12) = HCF(92,40) = HCF(224,92) = HCF(316,224) = HCF(856,316) .

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

Step 1: Since 987 > 4, we apply the division lemma to 987 and 4, to get

987 = 4 x 246 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: 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 4 and 987 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(987,4) .
