HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 878, 872 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 677, 878, 872 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 677, 878, 872 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 677, 878, 872 is 1.

HCF(677, 878, 872) = 1

HCF of 677, 878, 872 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 677, 878, 872 is 1.

Highest Common Factor of 677,878,872 using Euclid's algorithm

Highest Common Factor of 677,878,872 is 1

Step 1: Since 878 > 677, we apply the division lemma to 878 and 677, to get

878 = 677 x 1 + 201

Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 201 and 677, to get

677 = 201 x 3 + 74

Step 3: We consider the new divisor 201 and the new remainder 74, and apply the division lemma to get

201 = 74 x 2 + 53

We consider the new divisor 74 and the new remainder 53,and apply the division lemma to get

74 = 53 x 1 + 21

We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get

53 = 21 x 2 + 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 677 and 878 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(74,53) = HCF(201,74) = HCF(677,201) = HCF(878,677) .

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

Step 1: Since 872 > 1, we apply the division lemma to 872 and 1, to get

872 = 1 x 872 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 872 is 1

Notice that 1 = HCF(872,1) .
