HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 267, 680, 672 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 267, 680, 672 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 267, 680, 672 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 267, 680, 672 is 1.
HCF(267, 680, 672) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 267, 680, 672 is 1.
Step 1: Since 680 > 267, we apply the division lemma to 680 and 267, to get
680 = 267 x 2 + 146
Step 2: Since the reminder 267 ≠ 0, we apply division lemma to 146 and 267, to get
267 = 146 x 1 + 121
Step 3: We consider the new divisor 146 and the new remainder 121, and apply the division lemma to get
146 = 121 x 1 + 25
We consider the new divisor 121 and the new remainder 25,and apply the division lemma to get
121 = 25 x 4 + 21
We consider the new divisor 25 and the new remainder 21,and apply the division lemma to get
25 = 21 x 1 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 267 and 680 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(25,21) = HCF(121,25) = HCF(146,121) = HCF(267,146) = HCF(680,267) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 672 > 1, we apply the division lemma to 672 and 1, to get
672 = 1 x 672 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 672 is 1
Notice that 1 = HCF(672,1) .
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 267, 680, 672?
Answer: HCF of 267, 680, 672 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 267, 680, 672 using Euclid's Algorithm?
Answer: For arbitrary numbers 267, 680, 672 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
