HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 474, 831 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 474, 831 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 778, 474, 831 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 778, 474, 831 is 1.

HCF(778, 474, 831) = 1

Highest Common Factor of 778,474,831 using Euclid's algorithm

Highest Common Factor of 778,474,831 is 1

Step 1: Since 778 > 474, we apply the division lemma to 778 and 474, to get

778 = 474 x 1 + 304

Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 304 and 474, to get

474 = 304 x 1 + 170

Step 3: We consider the new divisor 304 and the new remainder 170, and apply the division lemma to get

304 = 170 x 1 + 134

We consider the new divisor 170 and the new remainder 134,and apply the division lemma to get

170 = 134 x 1 + 36

We consider the new divisor 134 and the new remainder 36,and apply the division lemma to get

134 = 36 x 3 + 26

We consider the new divisor 36 and the new remainder 26,and apply the division lemma to get

36 = 26 x 1 + 10

We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get

26 = 10 x 2 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 778 and 474 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(36,26) = HCF(134,36) = HCF(170,134) = HCF(304,170) = HCF(474,304) = HCF(778,474) .

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

Step 1: Since 831 > 2, we apply the division lemma to 831 and 2, to get

831 = 2 x 415 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 831 is 1

Notice that 1 = HCF(2,1) = HCF(831,2) .
