HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9725, 245 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 9725, 245 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 9725, 245 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 9725, 245 is 5.
HCF(9725, 245) = 5
HCF of 9725, 245 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9725, 245 is 5.
Highest Common Factor of 9725,245 is 5
Step 1: Since 9725 > 245, we apply the division lemma to 9725 and 245, to get
9725 = 245 x 39 + 170
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 170 and 245, to get
245 = 170 x 1 + 75
Step 3: We consider the new divisor 170 and the new remainder 75, and apply the division lemma to get
170 = 75 x 2 + 20
We consider the new divisor 75 and the new remainder 20,and apply the division lemma to get
75 = 20 x 3 + 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 9725 and 245 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(75,20) = HCF(170,75) = HCF(245,170) = HCF(9725,245) .
