HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 259, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 259, 755 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 672, 259, 755 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 672, 259, 755 is 1.
HCF(672, 259, 755) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 259, 755 is 1.
Step 1: Since 672 > 259, we apply the division lemma to 672 and 259, to get
672 = 259 x 2 + 154
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 154 and 259, to get
259 = 154 x 1 + 105
Step 3: We consider the new divisor 154 and the new remainder 105, and apply the division lemma to get
154 = 105 x 1 + 49
We consider the new divisor 105 and the new remainder 49,and apply the division lemma to get
105 = 49 x 2 + 7
We consider the new divisor 49 and the new remainder 7,and apply the division lemma to get
49 = 7 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 672 and 259 is 7
Notice that 7 = HCF(49,7) = HCF(105,49) = HCF(154,105) = HCF(259,154) = HCF(672,259) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 755 > 7, we apply the division lemma to 755 and 7, to get
755 = 7 x 107 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 755 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(755,7) .
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 672, 259, 755?
Answer: HCF of 672, 259, 755 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 672, 259, 755 using Euclid's Algorithm?
Answer: For arbitrary numbers 672, 259, 755 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
