HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7955, 8120 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 7955, 8120 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 7955, 8120 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 7955, 8120 is 5.
HCF(7955, 8120) = 5
HCF of 7955, 8120 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7955, 8120 is 5.
Highest Common Factor of 7955,8120 is 5
Step 1: Since 8120 > 7955, we apply the division lemma to 8120 and 7955, to get
8120 = 7955 x 1 + 165
Step 2: Since the reminder 7955 ≠ 0, we apply division lemma to 165 and 7955, to get
7955 = 165 x 48 + 35
Step 3: We consider the new divisor 165 and the new remainder 35, and apply the division lemma to get
165 = 35 x 4 + 25
We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get
35 = 25 x 1 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 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 7955 and 8120 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(165,35) = HCF(7955,165) = HCF(8120,7955) .
