HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 506 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 823, 506 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 823, 506 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 823, 506 is 1.
HCF(823, 506) = 1
HCF of 823, 506 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 823, 506 is 1.
Highest Common Factor of 823,506 is 1
Step 1: Since 823 > 506, we apply the division lemma to 823 and 506, to get
823 = 506 x 1 + 317
Step 2: Since the reminder 506 ≠ 0, we apply division lemma to 317 and 506, to get
506 = 317 x 1 + 189
Step 3: We consider the new divisor 317 and the new remainder 189, and apply the division lemma to get
317 = 189 x 1 + 128
We consider the new divisor 189 and the new remainder 128,and apply the division lemma to get
189 = 128 x 1 + 61
We consider the new divisor 128 and the new remainder 61,and apply the division lemma to get
128 = 61 x 2 + 6
We consider the new divisor 61 and the new remainder 6,and apply the division lemma to get
61 = 6 x 10 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 823 and 506 is 1
Notice that 1 = HCF(6,1) = HCF(61,6) = HCF(128,61) = HCF(189,128) = HCF(317,189) = HCF(506,317) = HCF(823,506) .
