HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 345, 22625 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 345, 22625 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 345, 22625 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 345, 22625 is 5.
HCF(345, 22625) = 5
HCF of 345, 22625 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 345, 22625 is 5.
Highest Common Factor of 345,22625 is 5
Step 1: Since 22625 > 345, we apply the division lemma to 22625 and 345, to get
22625 = 345 x 65 + 200
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 200 and 345, to get
345 = 200 x 1 + 145
Step 3: We consider the new divisor 200 and the new remainder 145, and apply the division lemma to get
200 = 145 x 1 + 55
We consider the new divisor 145 and the new remainder 55,and apply the division lemma to get
145 = 55 x 2 + 35
We consider the new divisor 55 and the new remainder 35,and apply the division lemma to get
55 = 35 x 1 + 20
We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get
35 = 20 x 1 + 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 345 and 22625 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(55,35) = HCF(145,55) = HCF(200,145) = HCF(345,200) = HCF(22625,345) .
