HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 467, 138, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 467, 138, 771 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 467, 138, 771 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 467, 138, 771 is 1.

HCF(467, 138, 771) = 1

Highest common factor (HCF) of 467, 138, 771 is 1.

Highest Common Factor of 467,138,771 using Euclid's algorithm

Highest Common Factor of 467,138,771 is 1

Step 1: Since 467 > 138, we apply the division lemma to 467 and 138, to get

467 = 138 x 3 + 53

Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 53 and 138, to get

138 = 53 x 2 + 32

Step 3: We consider the new divisor 53 and the new remainder 32, and apply the division lemma to get

53 = 32 x 1 + 21

We consider the new divisor 32 and the new remainder 21,and apply the division lemma to get

32 = 21 x 1 + 11

We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get

21 = 11 x 1 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 467 and 138 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(53,32) = HCF(138,53) = HCF(467,138) .

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

Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get

771 = 1 x 771 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1

Notice that 1 = HCF(771,1) .
