HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 243, 484 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 243, 484 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 243, 484 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 243, 484 is 1.
HCF(243, 484) = 1
HCF of 243, 484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 243, 484 is 1.
Highest Common Factor of 243,484 is 1
Step 1: Since 484 > 243, we apply the division lemma to 484 and 243, to get
484 = 243 x 1 + 241
Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 241 and 243, to get
243 = 241 x 1 + 2
Step 3: We consider the new divisor 241 and the new remainder 2, and apply the division lemma to get
241 = 2 x 120 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 243 and 484 is 1
Notice that 1 = HCF(2,1) = HCF(241,2) = HCF(243,241) = HCF(484,243) .
