HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 959, 556, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 959, 556, 57 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 959, 556, 57 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 959, 556, 57 is 1.

HCF(959, 556, 57) = 1

Highest common factor (HCF) of 959, 556, 57 is 1.

Highest Common Factor of 959,556,57 using Euclid's algorithm

Highest Common Factor of 959,556,57 is 1

Step 1: Since 959 > 556, we apply the division lemma to 959 and 556, to get

959 = 556 x 1 + 403

Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 403 and 556, to get

556 = 403 x 1 + 153

Step 3: We consider the new divisor 403 and the new remainder 153, and apply the division lemma to get

403 = 153 x 2 + 97

We consider the new divisor 153 and the new remainder 97,and apply the division lemma to get

153 = 97 x 1 + 56

We consider the new divisor 97 and the new remainder 56,and apply the division lemma to get

97 = 56 x 1 + 41

We consider the new divisor 56 and the new remainder 41,and apply the division lemma to get

56 = 41 x 1 + 15

We consider the new divisor 41 and the new remainder 15,and apply the division lemma to get

41 = 15 x 2 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 959 and 556 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(41,15) = HCF(56,41) = HCF(97,56) = HCF(153,97) = HCF(403,153) = HCF(556,403) = HCF(959,556) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
