HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 558, 947 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 558, 947 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 558, 947 is 1.

HCF(558, 947) = 1

HCF of 558, 947 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 558, 947 is 1.

Highest Common Factor of 558,947 using Euclid's algorithm

Highest Common Factor of 558,947 is 1

Step 1: Since 947 > 558, we apply the division lemma to 947 and 558, to get

947 = 558 x 1 + 389

Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 389 and 558, to get

558 = 389 x 1 + 169

Step 3: We consider the new divisor 389 and the new remainder 169, and apply the division lemma to get

389 = 169 x 2 + 51

We consider the new divisor 169 and the new remainder 51,and apply the division lemma to get

169 = 51 x 3 + 16

We consider the new divisor 51 and the new remainder 16,and apply the division lemma to get

51 = 16 x 3 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 558 and 947 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(51,16) = HCF(169,51) = HCF(389,169) = HCF(558,389) = HCF(947,558) .
