HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 403, 605, 982 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 403, 605, 982 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 403, 605, 982 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 403, 605, 982 is 1.
HCF(403, 605, 982) = 1
HCF of 403, 605, 982 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 403, 605, 982 is 1.
Highest Common Factor of 403,605,982 is 1
Step 1: Since 605 > 403, we apply the division lemma to 605 and 403, to get
605 = 403 x 1 + 202
Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 202 and 403, to get
403 = 202 x 1 + 201
Step 3: We consider the new divisor 202 and the new remainder 201, and apply the division lemma to get
202 = 201 x 1 + 1
We consider the new divisor 201 and the new remainder 1, and apply the division lemma to get
201 = 1 x 201 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 403 and 605 is 1
Notice that 1 = HCF(201,1) = HCF(202,201) = HCF(403,202) = HCF(605,403) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 1, we apply the division lemma to 982 and 1, to get
982 = 1 x 982 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 982 is 1
Notice that 1 = HCF(982,1) .
