HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 584 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 55, 584 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 55, 584 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 55, 584 is 1.

HCF(55, 584) = 1

Highest Common Factor of 55,584 using Euclid's algorithm

Highest Common Factor of 55,584 is 1

Step 1: Since 584 > 55, we apply the division lemma to 584 and 55, to get

584 = 55 x 10 + 34

Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 34 and 55, to get

55 = 34 x 1 + 21

Step 3: We consider the new divisor 34 and the new remainder 21, and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 55 and 584 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(55,34) = HCF(584,55) .
