HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7965, 2040 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 7965, 2040 is 15 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 7965, 2040 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 7965, 2040 is 15.
HCF(7965, 2040) = 15
HCF of 7965, 2040 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7965, 2040 is 15.
Highest Common Factor of 7965,2040 is 15
Step 1: Since 7965 > 2040, we apply the division lemma to 7965 and 2040, to get
7965 = 2040 x 3 + 1845
Step 2: Since the reminder 2040 ≠ 0, we apply division lemma to 1845 and 2040, to get
2040 = 1845 x 1 + 195
Step 3: We consider the new divisor 1845 and the new remainder 195, and apply the division lemma to get
1845 = 195 x 9 + 90
We consider the new divisor 195 and the new remainder 90,and apply the division lemma to get
195 = 90 x 2 + 15
We consider the new divisor 90 and the new remainder 15,and apply the division lemma to get
90 = 15 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 7965 and 2040 is 15
Notice that 15 = HCF(90,15) = HCF(195,90) = HCF(1845,195) = HCF(2040,1845) = HCF(7965,2040) .
