HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 475 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 475 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, 475 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, 475 is 5.
HCF(615, 475) = 5
HCF of 615, 475 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, 475 is 5.
Highest Common Factor of 615,475 is 5
Step 1: Since 615 > 475, we apply the division lemma to 615 and 475, to get
615 = 475 x 1 + 140
Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 140 and 475, to get
475 = 140 x 3 + 55
Step 3: We consider the new divisor 140 and the new remainder 55, and apply the division lemma to get
140 = 55 x 2 + 30
We consider the new divisor 55 and the new remainder 30,and apply the division lemma to get
55 = 30 x 1 + 25
We consider the new divisor 30 and the new remainder 25,and apply the division lemma to get
30 = 25 x 1 + 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 475 is 5
Notice that 5 = HCF(25,5) = HCF(30,25) = HCF(55,30) = HCF(140,55) = HCF(475,140) = HCF(615,475) .
