HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 814 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 470, 814 is 2 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 470, 814 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 470, 814 is 2.
HCF(470, 814) = 2
HCF of 470, 814 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 470, 814 is 2.
Highest Common Factor of 470,814 is 2
Step 1: Since 814 > 470, we apply the division lemma to 814 and 470, to get
814 = 470 x 1 + 344
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 344 and 470, to get
470 = 344 x 1 + 126
Step 3: We consider the new divisor 344 and the new remainder 126, and apply the division lemma to get
344 = 126 x 2 + 92
We consider the new divisor 126 and the new remainder 92,and apply the division lemma to get
126 = 92 x 1 + 34
We consider the new divisor 92 and the new remainder 34,and apply the division lemma to get
92 = 34 x 2 + 24
We consider the new divisor 34 and the new remainder 24,and apply the division lemma to get
34 = 24 x 1 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 470 and 814 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(34,24) = HCF(92,34) = HCF(126,92) = HCF(344,126) = HCF(470,344) = HCF(814,470) .
