HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 331, 936, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 331, 936, 861 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 331, 936, 861 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 331, 936, 861 is 1.

HCF(331, 936, 861) = 1

Highest common factor (HCF) of 331, 936, 861 is 1.

Highest Common Factor of 331,936,861 using Euclid's algorithm

Highest Common Factor of 331,936,861 is 1

Step 1: Since 936 > 331, we apply the division lemma to 936 and 331, to get

936 = 331 x 2 + 274

Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 274 and 331, to get

331 = 274 x 1 + 57

Step 3: We consider the new divisor 274 and the new remainder 57, and apply the division lemma to get

274 = 57 x 4 + 46

We consider the new divisor 57 and the new remainder 46,and apply the division lemma to get

57 = 46 x 1 + 11

We consider the new divisor 46 and the new remainder 11,and apply the division lemma to get

46 = 11 x 4 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 331 and 936 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(46,11) = HCF(57,46) = HCF(274,57) = HCF(331,274) = HCF(936,331) .

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

Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get

861 = 1 x 861 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1

Notice that 1 = HCF(861,1) .
