HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 940, 260, 615 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 940, 260, 615 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 940, 260, 615 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 940, 260, 615 is 5.
HCF(940, 260, 615) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 940, 260, 615 is 5.
Step 1: Since 940 > 260, we apply the division lemma to 940 and 260, to get
940 = 260 x 3 + 160
Step 2: Since the reminder 260 ≠ 0, we apply division lemma to 160 and 260, to get
260 = 160 x 1 + 100
Step 3: We consider the new divisor 160 and the new remainder 100, and apply the division lemma to get
160 = 100 x 1 + 60
We consider the new divisor 100 and the new remainder 60,and apply the division lemma to get
100 = 60 x 1 + 40
We consider the new divisor 60 and the new remainder 40,and apply the division lemma to get
60 = 40 x 1 + 20
We consider the new divisor 40 and the new remainder 20,and apply the division lemma to get
40 = 20 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 940 and 260 is 20
Notice that 20 = HCF(40,20) = HCF(60,40) = HCF(100,60) = HCF(160,100) = HCF(260,160) = HCF(940,260) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 20, we apply the division lemma to 615 and 20, to get
615 = 20 x 30 + 15
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 15 and 20, to get
20 = 15 x 1 + 5
Step 3: We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 20 and 615 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(615,20) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 940, 260, 615?
Answer: HCF of 940, 260, 615 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 940, 260, 615 using Euclid's Algorithm?
Answer: For arbitrary numbers 940, 260, 615 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
