HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9515, 2682, 78085 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9515, 2682, 78085 is 1 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 9515, 2682, 78085 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 9515, 2682, 78085 is 1.
HCF(9515, 2682, 78085) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9515, 2682, 78085 is 1.
Step 1: Since 9515 > 2682, we apply the division lemma to 9515 and 2682, to get
9515 = 2682 x 3 + 1469
Step 2: Since the reminder 2682 ≠ 0, we apply division lemma to 1469 and 2682, to get
2682 = 1469 x 1 + 1213
Step 3: We consider the new divisor 1469 and the new remainder 1213, and apply the division lemma to get
1469 = 1213 x 1 + 256
We consider the new divisor 1213 and the new remainder 256,and apply the division lemma to get
1213 = 256 x 4 + 189
We consider the new divisor 256 and the new remainder 189,and apply the division lemma to get
256 = 189 x 1 + 67
We consider the new divisor 189 and the new remainder 67,and apply the division lemma to get
189 = 67 x 2 + 55
We consider the new divisor 67 and the new remainder 55,and apply the division lemma to get
67 = 55 x 1 + 12
We consider the new divisor 55 and the new remainder 12,and apply the division lemma to get
55 = 12 x 4 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9515 and 2682 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(55,12) = HCF(67,55) = HCF(189,67) = HCF(256,189) = HCF(1213,256) = HCF(1469,1213) = HCF(2682,1469) = HCF(9515,2682) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78085 > 1, we apply the division lemma to 78085 and 1, to get
78085 = 1 x 78085 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78085 is 1
Notice that 1 = HCF(78085,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
