HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 910 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 910 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 615, 910 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, 910 is 5.
HCF(615, 910) = 5
HCF of 615, 910 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, 910 is 5.
Highest Common Factor of 615,910 is 5
Step 1: Since 910 > 615, we apply the division lemma to 910 and 615, to get
910 = 615 x 1 + 295
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 295 and 615, to get
615 = 295 x 2 + 25
Step 3: We consider the new divisor 295 and the new remainder 25, and apply the division lemma to get
295 = 25 x 11 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 615 and 910 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(295,25) = HCF(615,295) = HCF(910,615) .
