HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 408, 176 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 287, 408, 176 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 287, 408, 176 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 287, 408, 176 is 1.

HCF(287, 408, 176) = 1

Highest common factor (HCF) of 287, 408, 176 is 1.

Highest Common Factor of 287,408,176 using Euclid's algorithm

Highest Common Factor of 287,408,176 is 1

Step 1: Since 408 > 287, we apply the division lemma to 408 and 287, to get

408 = 287 x 1 + 121

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 121 and 287, to get

287 = 121 x 2 + 45

Step 3: We consider the new divisor 121 and the new remainder 45, and apply the division lemma to get

121 = 45 x 2 + 31

We consider the new divisor 45 and the new remainder 31,and apply the division lemma to get

45 = 31 x 1 + 14

We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get

31 = 14 x 2 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 287 and 408 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(121,45) = HCF(287,121) = HCF(408,287) .

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

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

176 = 1 x 176 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 176 is 1

Notice that 1 = HCF(176,1) .
