HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 247, 439 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, 439 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, 439 is 1.
HCF(247, 439) = 1
HCF of 247, 439 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 247, 439 is 1.
Highest Common Factor of 247,439 is 1
Step 1: Since 439 > 247, we apply the division lemma to 439 and 247, to get
439 = 247 x 1 + 192
Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 192 and 247, to get
247 = 192 x 1 + 55
Step 3: We consider the new divisor 192 and the new remainder 55, and apply the division lemma to get
192 = 55 x 3 + 27
We consider the new divisor 55 and the new remainder 27,and apply the division lemma to get
55 = 27 x 2 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 439 is 1
Notice that 1 = HCF(27,1) = HCF(55,27) = HCF(192,55) = HCF(247,192) = HCF(439,247) .
