HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 963, 556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 963, 556 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 963, 556 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 963, 556 is 1.

HCF(963, 556) = 1

HCF of 963, 556 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 963, 556 is 1.

Highest Common Factor of 963,556 using Euclid's algorithm

Highest Common Factor of 963,556 is 1

Step 1: Since 963 > 556, we apply the division lemma to 963 and 556, to get

963 = 556 x 1 + 407

Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 407 and 556, to get

556 = 407 x 1 + 149

Step 3: We consider the new divisor 407 and the new remainder 149, and apply the division lemma to get

407 = 149 x 2 + 109

We consider the new divisor 149 and the new remainder 109,and apply the division lemma to get

149 = 109 x 1 + 40

We consider the new divisor 109 and the new remainder 40,and apply the division lemma to get

109 = 40 x 2 + 29

We consider the new divisor 40 and the new remainder 29,and apply the division lemma to get

40 = 29 x 1 + 11

We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get

29 = 11 x 2 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 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 963 and 556 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(40,29) = HCF(109,40) = HCF(149,109) = HCF(407,149) = HCF(556,407) = HCF(963,556) .
