HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 469 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 469 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 870, 469 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 870, 469 is 1.
HCF(870, 469) = 1
HCF of 870, 469 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 469 is 1.
Highest Common Factor of 870,469 is 1
Step 1: Since 870 > 469, we apply the division lemma to 870 and 469, to get
870 = 469 x 1 + 401
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 401 and 469, to get
469 = 401 x 1 + 68
Step 3: We consider the new divisor 401 and the new remainder 68, and apply the division lemma to get
401 = 68 x 5 + 61
We consider the new divisor 68 and the new remainder 61,and apply the division lemma to get
68 = 61 x 1 + 7
We consider the new divisor 61 and the new remainder 7,and apply the division lemma to get
61 = 7 x 8 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 870 and 469 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(61,7) = HCF(68,61) = HCF(401,68) = HCF(469,401) = HCF(870,469) .
