HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 320 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 777, 320 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 777, 320 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 777, 320 is 1.
HCF(777, 320) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 777, 320 is 1.
Step 1: Since 777 > 320, we apply the division lemma to 777 and 320, to get
777 = 320 x 2 + 137
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 137 and 320, to get
320 = 137 x 2 + 46
Step 3: We consider the new divisor 137 and the new remainder 46, and apply the division lemma to get
137 = 46 x 2 + 45
We consider the new divisor 46 and the new remainder 45,and apply the division lemma to get
46 = 45 x 1 + 1
We consider the new divisor 45 and the new remainder 1,and apply the division lemma to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 777 and 320 is 1
Notice that 1 = HCF(45,1) = HCF(46,45) = HCF(137,46) = HCF(320,137) = HCF(777,320) .
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 777, 320?
Answer: HCF of 777, 320 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 777, 320 using Euclid's Algorithm?
Answer: For arbitrary numbers 777, 320 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
