HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 176, 678, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 176, 678, 857 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 176, 678, 857 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 176, 678, 857 is 1.

HCF(176, 678, 857) = 1

Highest common factor (HCF) of 176, 678, 857 is 1.

Highest Common Factor of 176,678,857 using Euclid's algorithm

Highest Common Factor of 176,678,857 is 1

Step 1: Since 678 > 176, we apply the division lemma to 678 and 176, to get

678 = 176 x 3 + 150

Step 2: Since the reminder 176 ≠ 0, we apply division lemma to 150 and 176, to get

176 = 150 x 1 + 26

Step 3: We consider the new divisor 150 and the new remainder 26, and apply the division lemma to get

150 = 26 x 5 + 20

We consider the new divisor 26 and the new remainder 20,and apply the division lemma to get

26 = 20 x 1 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 176 and 678 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(26,20) = HCF(150,26) = HCF(176,150) = HCF(678,176) .


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

Step 1: Since 857 > 2, we apply the division lemma to 857 and 2, to get

857 = 2 x 428 + 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 857 is 1

Notice that 1 = HCF(2,1) = HCF(857,2) .
