HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 845 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 845 is 5 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 480, 845 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 480, 845 is 5.
HCF(480, 845) = 5
HCF of 480, 845 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 480, 845 is 5.
Highest Common Factor of 480,845 is 5
Step 1: Since 845 > 480, we apply the division lemma to 845 and 480, to get
845 = 480 x 1 + 365
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 365 and 480, to get
480 = 365 x 1 + 115
Step 3: We consider the new divisor 365 and the new remainder 115, and apply the division lemma to get
365 = 115 x 3 + 20
We consider the new divisor 115 and the new remainder 20,and apply the division lemma to get
115 = 20 x 5 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 480 and 845 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(115,20) = HCF(365,115) = HCF(480,365) = HCF(845,480) .
