HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 877, 178 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 877, 178 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 877, 178 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 877, 178 is 1.

HCF(877, 178) = 1

HCF of 877, 178 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 877, 178 is 1.

Highest Common Factor of 877,178 using Euclid's algorithm

Highest Common Factor of 877,178 is 1

Step 1: Since 877 > 178, we apply the division lemma to 877 and 178, to get

877 = 178 x 4 + 165

Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 165 and 178, to get

178 = 165 x 1 + 13

Step 3: We consider the new divisor 165 and the new remainder 13, and apply the division lemma to get

165 = 13 x 12 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 877 and 178 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(165,13) = HCF(178,165) = HCF(877,178) .
