HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 336 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 336 is 7 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 791, 336 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 791, 336 is 7.
HCF(791, 336) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 336 is 7.
Step 1: Since 791 > 336, we apply the division lemma to 791 and 336, to get
791 = 336 x 2 + 119
Step 2: Since the reminder 336 ≠ 0, we apply division lemma to 119 and 336, to get
336 = 119 x 2 + 98
Step 3: We consider the new divisor 119 and the new remainder 98, and apply the division lemma to get
119 = 98 x 1 + 21
We consider the new divisor 98 and the new remainder 21,and apply the division lemma to get
98 = 21 x 4 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 791 and 336 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(98,21) = HCF(119,98) = HCF(336,119) = HCF(791,336) .
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 791, 336?
Answer: HCF of 791, 336 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 791, 336 using Euclid's Algorithm?
Answer: For arbitrary numbers 791, 336 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
