HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 695, 195 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 695, 195 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, 695, 195 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, 695, 195 is 5.
HCF(615, 695, 195) = 5
HCF of 615, 695, 195 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, 695, 195 is 5.
Highest Common Factor of 615,695,195 is 5
Step 1: Since 695 > 615, we apply the division lemma to 695 and 615, to get
695 = 615 x 1 + 80
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 80 and 615, to get
615 = 80 x 7 + 55
Step 3: We consider the new divisor 80 and the new remainder 55, and apply the division lemma to get
80 = 55 x 1 + 25
We consider the new divisor 55 and the new remainder 25,and apply the division lemma to get
55 = 25 x 2 + 5
We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get
25 = 5 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 615 and 695 is 5
Notice that 5 = HCF(25,5) = HCF(55,25) = HCF(80,55) = HCF(615,80) = HCF(695,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 195 > 5, we apply the division lemma to 195 and 5, to get
195 = 5 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 195 is 5
Notice that 5 = HCF(195,5) .
