HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 558, 842 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 558, 842 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 949, 558, 842 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 949, 558, 842 is 1.

HCF(949, 558, 842) = 1

Highest common factor (HCF) of 949, 558, 842 is 1.

Highest Common Factor of 949,558,842 using Euclid's algorithm

Highest Common Factor of 949,558,842 is 1

Step 1: Since 949 > 558, we apply the division lemma to 949 and 558, to get

949 = 558 x 1 + 391

Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 391 and 558, to get

558 = 391 x 1 + 167

Step 3: We consider the new divisor 391 and the new remainder 167, and apply the division lemma to get

391 = 167 x 2 + 57

We consider the new divisor 167 and the new remainder 57,and apply the division lemma to get

167 = 57 x 2 + 53

We consider the new divisor 57 and the new remainder 53,and apply the division lemma to get

57 = 53 x 1 + 4

We consider the new divisor 53 and the new remainder 4,and apply the division lemma to get

53 = 4 x 13 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 558 is 1

Notice that 1 = HCF(4,1) = HCF(53,4) = HCF(57,53) = HCF(167,57) = HCF(391,167) = HCF(558,391) = HCF(949,558) .

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

Step 1: Since 842 > 1, we apply the division lemma to 842 and 1, to get

842 = 1 x 842 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 842 is 1

Notice that 1 = HCF(842,1) .
