HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 483 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 821, 483 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 821, 483 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 821, 483 is 1.
HCF(821, 483) = 1
HCF of 821, 483 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 821, 483 is 1.
Highest Common Factor of 821,483 is 1
Step 1: Since 821 > 483, we apply the division lemma to 821 and 483, to get
821 = 483 x 1 + 338
Step 2: Since the reminder 483 ≠ 0, we apply division lemma to 338 and 483, to get
483 = 338 x 1 + 145
Step 3: We consider the new divisor 338 and the new remainder 145, and apply the division lemma to get
338 = 145 x 2 + 48
We consider the new divisor 145 and the new remainder 48,and apply the division lemma to get
145 = 48 x 3 + 1
We consider the new divisor 48 and the new remainder 1,and apply the division lemma to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 821 and 483 is 1
Notice that 1 = HCF(48,1) = HCF(145,48) = HCF(338,145) = HCF(483,338) = HCF(821,483) .
