HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 474, 823 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 474, 823 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 474, 823 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 474, 823 is 1.
HCF(474, 823) = 1
HCF of 474, 823 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 474, 823 is 1.
Highest Common Factor of 474,823 is 1
Step 1: Since 823 > 474, we apply the division lemma to 823 and 474, to get
823 = 474 x 1 + 349
Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 349 and 474, to get
474 = 349 x 1 + 125
Step 3: We consider the new divisor 349 and the new remainder 125, and apply the division lemma to get
349 = 125 x 2 + 99
We consider the new divisor 125 and the new remainder 99,and apply the division lemma to get
125 = 99 x 1 + 26
We consider the new divisor 99 and the new remainder 26,and apply the division lemma to get
99 = 26 x 3 + 21
We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 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 474 and 823 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(99,26) = HCF(125,99) = HCF(349,125) = HCF(474,349) = HCF(823,474) .
