HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 329, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 329, 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 247, 329, 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 247, 329, 279 is 1.
HCF(247, 329, 279) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 329, 279 is 1.
Step 1: Since 329 > 247, we apply the division lemma to 329 and 247, to get
329 = 247 x 1 + 82
Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 82 and 247, to get
247 = 82 x 3 + 1
Step 3: We consider the new divisor 82 and the new remainder 1, and apply the division lemma to get
82 = 1 x 82 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 329 is 1
Notice that 1 = HCF(82,1) = HCF(247,82) = HCF(329,247) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 1, we apply the division lemma to 279 and 1, to get
279 = 1 x 279 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 279 is 1
Notice that 1 = HCF(279,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
