HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 47 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 845, 47 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 845, 47 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 845, 47 is 1.
HCF(845, 47) = 1
HCF of 845, 47 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 845, 47 is 1.
Highest Common Factor of 845,47 is 1
Step 1: Since 845 > 47, we apply the division lemma to 845 and 47, to get
845 = 47 x 17 + 46
Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 46 and 47, to get
47 = 46 x 1 + 1
Step 3: We consider the new divisor 46 and the new remainder 1, and apply the division lemma to get
46 = 1 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 845 and 47 is 1
Notice that 1 = HCF(46,1) = HCF(47,46) = HCF(845,47) .
