HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 368, 816, 716 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 368, 816, 716 is 4 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 368, 816, 716 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 368, 816, 716 is 4.
HCF(368, 816, 716) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 368, 816, 716 is 4.
Step 1: Since 816 > 368, we apply the division lemma to 816 and 368, to get
816 = 368 x 2 + 80
Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 80 and 368, to get
368 = 80 x 4 + 48
Step 3: We consider the new divisor 80 and the new remainder 48, and apply the division lemma to get
80 = 48 x 1 + 32
We consider the new divisor 48 and the new remainder 32,and apply the division lemma to get
48 = 32 x 1 + 16
We consider the new divisor 32 and the new remainder 16,and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 368 and 816 is 16
Notice that 16 = HCF(32,16) = HCF(48,32) = HCF(80,48) = HCF(368,80) = HCF(816,368) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 16, we apply the division lemma to 716 and 16, to get
716 = 16 x 44 + 12
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 12 and 16, to get
16 = 12 x 1 + 4
Step 3: We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 16 and 716 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(716,16) .
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 368, 816, 716?
Answer: HCF of 368, 816, 716 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 368, 816, 716 using Euclid's Algorithm?
Answer: For arbitrary numbers 368, 816, 716 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
