HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 283, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 283, 455 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 283, 455 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 283, 455 is 1.
HCF(283, 455) = 1
HCF of 283, 455 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 283, 455 is 1.
Highest Common Factor of 283,455 is 1
Step 1: Since 455 > 283, we apply the division lemma to 455 and 283, to get
455 = 283 x 1 + 172
Step 2: Since the reminder 283 ≠ 0, we apply division lemma to 172 and 283, to get
283 = 172 x 1 + 111
Step 3: We consider the new divisor 172 and the new remainder 111, and apply the division lemma to get
172 = 111 x 1 + 61
We consider the new divisor 111 and the new remainder 61,and apply the division lemma to get
111 = 61 x 1 + 50
We consider the new divisor 61 and the new remainder 50,and apply the division lemma to get
61 = 50 x 1 + 11
We consider the new divisor 50 and the new remainder 11,and apply the division lemma to get
50 = 11 x 4 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 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 283 and 455 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(50,11) = HCF(61,50) = HCF(111,61) = HCF(172,111) = HCF(283,172) = HCF(455,283) .
