HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 563 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 905, 563 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 905, 563 is 1.
HCF(905, 563) = 1
HCF of 905, 563 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 563 is 1.
Highest Common Factor of 905,563 is 1
Step 1: Since 905 > 563, we apply the division lemma to 905 and 563, to get
905 = 563 x 1 + 342
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 342 and 563, to get
563 = 342 x 1 + 221
Step 3: We consider the new divisor 342 and the new remainder 221, and apply the division lemma to get
342 = 221 x 1 + 121
We consider the new divisor 221 and the new remainder 121,and apply the division lemma to get
221 = 121 x 1 + 100
We consider the new divisor 121 and the new remainder 100,and apply the division lemma to get
121 = 100 x 1 + 21
We consider the new divisor 100 and the new remainder 21,and apply the division lemma to get
100 = 21 x 4 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 905 and 563 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(100,21) = HCF(121,100) = HCF(221,121) = HCF(342,221) = HCF(563,342) = HCF(905,563) .
