HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 976, 680, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 976, 680, 279 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 976, 680, 279 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 976, 680, 279 is 1.
HCF(976, 680, 279) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 976, 680, 279 is 1.
Step 1: Since 976 > 680, we apply the division lemma to 976 and 680, to get
976 = 680 x 1 + 296
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 296 and 680, to get
680 = 296 x 2 + 88
Step 3: We consider the new divisor 296 and the new remainder 88, and apply the division lemma to get
296 = 88 x 3 + 32
We consider the new divisor 88 and the new remainder 32,and apply the division lemma to get
88 = 32 x 2 + 24
We consider the new divisor 32 and the new remainder 24,and apply the division lemma to get
32 = 24 x 1 + 8
We consider the new divisor 24 and the new remainder 8,and apply the division lemma to get
24 = 8 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 976 and 680 is 8
Notice that 8 = HCF(24,8) = HCF(32,24) = HCF(88,32) = HCF(296,88) = HCF(680,296) = HCF(976,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 8, we apply the division lemma to 279 and 8, to get
279 = 8 x 34 + 7
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 7 and 8, to get
8 = 7 x 1 + 1
Step 3: We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 279 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(279,8) .
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 976, 680, 279?
Answer: HCF of 976, 680, 279 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 976, 680, 279 using Euclid's Algorithm?
Answer: For arbitrary numbers 976, 680, 279 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
