HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 704, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 871, 704, 780 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 871, 704, 780 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 871, 704, 780 is 1.

HCF(871, 704, 780) = 1

Highest common factor (HCF) of 871, 704, 780 is 1.

Highest Common Factor of 871,704,780 using Euclid's algorithm

Highest Common Factor of 871,704,780 is 1

Step 1: Since 871 > 704, we apply the division lemma to 871 and 704, to get

871 = 704 x 1 + 167

Step 2: Since the reminder 704 ≠ 0, we apply division lemma to 167 and 704, to get

704 = 167 x 4 + 36

Step 3: We consider the new divisor 167 and the new remainder 36, and apply the division lemma to get

167 = 36 x 4 + 23

We consider the new divisor 36 and the new remainder 23,and apply the division lemma to get

36 = 23 x 1 + 13

We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get

23 = 13 x 1 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 704 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(36,23) = HCF(167,36) = HCF(704,167) = HCF(871,704) .

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

Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get

780 = 1 x 780 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1

Notice that 1 = HCF(780,1) .
