HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 875, 815 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 875, 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 275, 875, 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 275, 875, 815 is 5.
HCF(275, 875, 815) = 5
HCF of 275, 875, 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 275, 875, 815 is 5.
Highest Common Factor of 275,875,815 is 5
Step 1: Since 875 > 275, we apply the division lemma to 875 and 275, to get
875 = 275 x 3 + 50
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 50 and 275, to get
275 = 50 x 5 + 25
Step 3: We consider the new divisor 50 and the new remainder 25, and apply the division lemma to get
50 = 25 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 275 and 875 is 25
Notice that 25 = HCF(50,25) = HCF(275,50) = HCF(875,275) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 25, we apply the division lemma to 815 and 25, to get
815 = 25 x 32 + 15
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 15 and 25, to get
25 = 15 x 1 + 10
Step 3: We consider the new divisor 15 and the new remainder 10, and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 25 and 815 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(815,25) .
