HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 55, 14 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 84, 55, 14 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 84, 55, 14 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 84, 55, 14 is 1.

HCF(84, 55, 14) = 1

HCF of 84, 55, 14 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 84, 55, 14 is 1.

Highest Common Factor of 84,55,14 using Euclid's algorithm

Highest Common Factor of 84,55,14 is 1

Step 1: Since 84 > 55, we apply the division lemma to 84 and 55, to get

84 = 55 x 1 + 29

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 29 and 55, to get

55 = 29 x 1 + 26

Step 3: We consider the new divisor 29 and the new remainder 26, and apply the division lemma to get

29 = 26 x 1 + 3

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

26 = 3 x 8 + 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 84 and 55 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(84,55) .

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

Step 1: Since 14 > 1, we apply the division lemma to 14 and 1, to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 14 is 1

Notice that 1 = HCF(14,1) .
