HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 863 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 556, 863 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 556, 863 is 1.
HCF(556, 863) = 1
HCF of 556, 863 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 863 is 1.
Highest Common Factor of 556,863 is 1
Step 1: Since 863 > 556, we apply the division lemma to 863 and 556, to get
863 = 556 x 1 + 307
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 307 and 556, to get
556 = 307 x 1 + 249
Step 3: We consider the new divisor 307 and the new remainder 249, and apply the division lemma to get
307 = 249 x 1 + 58
We consider the new divisor 249 and the new remainder 58,and apply the division lemma to get
249 = 58 x 4 + 17
We consider the new divisor 58 and the new remainder 17,and apply the division lemma to get
58 = 17 x 3 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 556 and 863 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(58,17) = HCF(249,58) = HCF(307,249) = HCF(556,307) = HCF(863,556) .
