HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 935, 815 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 935, 815 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 935, 815 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 935, 815 is 5.
HCF(935, 815) = 5
HCF of 935, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 935, 815 is 5.
Highest Common Factor of 935,815 is 5
Step 1: Since 935 > 815, we apply the division lemma to 935 and 815, to get
935 = 815 x 1 + 120
Step 2: Since the reminder 815 ≠ 0, we apply division lemma to 120 and 815, to get
815 = 120 x 6 + 95
Step 3: We consider the new divisor 120 and the new remainder 95, and apply the division lemma to get
120 = 95 x 1 + 25
We consider the new divisor 95 and the new remainder 25,and apply the division lemma to get
95 = 25 x 3 + 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 935 and 815 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(95,25) = HCF(120,95) = HCF(815,120) = HCF(935,815) .
