HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 716, 978 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 716, 978 is 2 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 716, 978 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 716, 978 is 2.
HCF(716, 978) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 716, 978 is 2.
Step 1: Since 978 > 716, we apply the division lemma to 978 and 716, to get
978 = 716 x 1 + 262
Step 2: Since the reminder 716 ≠ 0, we apply division lemma to 262 and 716, to get
716 = 262 x 2 + 192
Step 3: We consider the new divisor 262 and the new remainder 192, and apply the division lemma to get
262 = 192 x 1 + 70
We consider the new divisor 192 and the new remainder 70,and apply the division lemma to get
192 = 70 x 2 + 52
We consider the new divisor 70 and the new remainder 52,and apply the division lemma to get
70 = 52 x 1 + 18
We consider the new divisor 52 and the new remainder 18,and apply the division lemma to get
52 = 18 x 2 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 716 and 978 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(52,18) = HCF(70,52) = HCF(192,70) = HCF(262,192) = HCF(716,262) = HCF(978,716) .
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 716, 978?
Answer: HCF of 716, 978 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 716, 978 using Euclid's Algorithm?
Answer: For arbitrary numbers 716, 978 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
