HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 417 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 417 is 3 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 615, 417 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 615, 417 is 3.
HCF(615, 417) = 3
HCF of 615, 417 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 417 is 3.
Highest Common Factor of 615,417 is 3
Step 1: Since 615 > 417, we apply the division lemma to 615 and 417, to get
615 = 417 x 1 + 198
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 198 and 417, to get
417 = 198 x 2 + 21
Step 3: We consider the new divisor 198 and the new remainder 21, and apply the division lemma to get
198 = 21 x 9 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 417 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(198,21) = HCF(417,198) = HCF(615,417) .
