HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 463, 178, 84 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 463, 178, 84 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 463, 178, 84 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 463, 178, 84 is 1.

HCF(463, 178, 84) = 1

Highest common factor (HCF) of 463, 178, 84 is 1.

Highest Common Factor of 463,178,84 using Euclid's algorithm

Highest Common Factor of 463,178,84 is 1

Step 1: Since 463 > 178, we apply the division lemma to 463 and 178, to get

463 = 178 x 2 + 107

Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 107 and 178, to get

178 = 107 x 1 + 71

Step 3: We consider the new divisor 107 and the new remainder 71, and apply the division lemma to get

107 = 71 x 1 + 36

We consider the new divisor 71 and the new remainder 36,and apply the division lemma to get

71 = 36 x 1 + 35

We consider the new divisor 36 and the new remainder 35,and apply the division lemma to get

36 = 35 x 1 + 1

We consider the new divisor 35 and the new remainder 1,and apply the division lemma to get

35 = 1 x 35 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 463 and 178 is 1

Notice that 1 = HCF(35,1) = HCF(36,35) = HCF(71,36) = HCF(107,71) = HCF(178,107) = HCF(463,178) .

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

Step 1: Since 84 > 1, we apply the division lemma to 84 and 1, to get

84 = 1 x 84 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 84 is 1

Notice that 1 = HCF(84,1) .
