HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 762, 278, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 762, 278, 71 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 762, 278, 71 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 762, 278, 71 is 1.

HCF(762, 278, 71) = 1

Highest common factor (HCF) of 762, 278, 71 is 1.

Highest Common Factor of 762,278,71 using Euclid's algorithm

Highest Common Factor of 762,278,71 is 1

Step 1: Since 762 > 278, we apply the division lemma to 762 and 278, to get

762 = 278 x 2 + 206

Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 206 and 278, to get

278 = 206 x 1 + 72

Step 3: We consider the new divisor 206 and the new remainder 72, and apply the division lemma to get

206 = 72 x 2 + 62

We consider the new divisor 72 and the new remainder 62,and apply the division lemma to get

72 = 62 x 1 + 10

We consider the new divisor 62 and the new remainder 10,and apply the division lemma to get

62 = 10 x 6 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 762 and 278 is 2

Notice that 2 = HCF(10,2) = HCF(62,10) = HCF(72,62) = HCF(206,72) = HCF(278,206) = HCF(762,278) .

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

Step 1: Since 71 > 2, we apply the division lemma to 71 and 2, to get

71 = 2 x 35 + 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 71 is 1

Notice that 1 = HCF(2,1) = HCF(71,2) .
