HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5085, 7665 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 5085, 7665 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 5085, 7665 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 5085, 7665 is 15.
HCF(5085, 7665) = 15
HCF of 5085, 7665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5085, 7665 is 15.
Highest Common Factor of 5085,7665 is 15
Step 1: Since 7665 > 5085, we apply the division lemma to 7665 and 5085, to get
7665 = 5085 x 1 + 2580
Step 2: Since the reminder 5085 ≠ 0, we apply division lemma to 2580 and 5085, to get
5085 = 2580 x 1 + 2505
Step 3: We consider the new divisor 2580 and the new remainder 2505, and apply the division lemma to get
2580 = 2505 x 1 + 75
We consider the new divisor 2505 and the new remainder 75,and apply the division lemma to get
2505 = 75 x 33 + 30
We consider the new divisor 75 and the new remainder 30,and apply the division lemma to get
75 = 30 x 2 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 5085 and 7665 is 15
Notice that 15 = HCF(30,15) = HCF(75,30) = HCF(2505,75) = HCF(2580,2505) = HCF(5085,2580) = HCF(7665,5085) .
