HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 531, 854 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 531, 854 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 857, 531, 854 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 857, 531, 854 is 1.

HCF(857, 531, 854) = 1

Highest common factor (HCF) of 857, 531, 854 is 1.

Highest Common Factor of 857,531,854 using Euclid's algorithm

Highest Common Factor of 857,531,854 is 1

Step 1: Since 857 > 531, we apply the division lemma to 857 and 531, to get

857 = 531 x 1 + 326

Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 326 and 531, to get

531 = 326 x 1 + 205

Step 3: We consider the new divisor 326 and the new remainder 205, and apply the division lemma to get

326 = 205 x 1 + 121

We consider the new divisor 205 and the new remainder 121,and apply the division lemma to get

205 = 121 x 1 + 84

We consider the new divisor 121 and the new remainder 84,and apply the division lemma to get

121 = 84 x 1 + 37

We consider the new divisor 84 and the new remainder 37,and apply the division lemma to get

84 = 37 x 2 + 10

We consider the new divisor 37 and the new remainder 10,and apply the division lemma to get

37 = 10 x 3 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

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 857 and 531 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(37,10) = HCF(84,37) = HCF(121,84) = HCF(205,121) = HCF(326,205) = HCF(531,326) = HCF(857,531) .

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

Step 1: Since 854 > 1, we apply the division lemma to 854 and 1, to get

854 = 1 x 854 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 854 is 1

Notice that 1 = HCF(854,1) .
