HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 173 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 485, 173 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 485, 173 is 1.
HCF(485, 173) = 1
HCF of 485, 173 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 173 is 1.
Highest Common Factor of 485,173 is 1
Step 1: Since 485 > 173, we apply the division lemma to 485 and 173, to get
485 = 173 x 2 + 139
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 139 and 173, to get
173 = 139 x 1 + 34
Step 3: We consider the new divisor 139 and the new remainder 34, and apply the division lemma to get
139 = 34 x 4 + 3
We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get
34 = 3 x 11 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 173 is 1
Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(139,34) = HCF(173,139) = HCF(485,173) .
