HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 940, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 831, 940, 909 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 831, 940, 909 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 831, 940, 909 is 1.

HCF(831, 940, 909) = 1

HCF of 831, 940, 909 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 831, 940, 909 is 1.

Highest Common Factor of 831,940,909 using Euclid's algorithm

Highest Common Factor of 831,940,909 is 1

Step 1: Since 940 > 831, we apply the division lemma to 940 and 831, to get

940 = 831 x 1 + 109

Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 109 and 831, to get

831 = 109 x 7 + 68

Step 3: We consider the new divisor 109 and the new remainder 68, and apply the division lemma to get

109 = 68 x 1 + 41

We consider the new divisor 68 and the new remainder 41,and apply the division lemma to get

68 = 41 x 1 + 27

We consider the new divisor 41 and the new remainder 27,and apply the division lemma to get

41 = 27 x 1 + 14

We consider the new divisor 27 and the new remainder 14,and apply the division lemma to get

27 = 14 x 1 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 831 and 940 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(41,27) = HCF(68,41) = HCF(109,68) = HCF(831,109) = HCF(940,831) .


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

Step 1: Since 909 > 1, we apply the division lemma to 909 and 1, to get

909 = 1 x 909 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 909 is 1

Notice that 1 = HCF(909,1) .
