HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 582, 258, 21 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 582, 258, 21 is 3 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 582, 258, 21 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 582, 258, 21 is 3.
HCF(582, 258, 21) = 3
HCF of 582, 258, 21 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 582, 258, 21 is 3.
Highest Common Factor of 582,258,21 is 3
Step 1: Since 582 > 258, we apply the division lemma to 582 and 258, to get
582 = 258 x 2 + 66
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 66 and 258, to get
258 = 66 x 3 + 60
Step 3: We consider the new divisor 66 and the new remainder 60, and apply the division lemma to get
66 = 60 x 1 + 6
We consider the new divisor 60 and the new remainder 6, and apply the division lemma to get
60 = 6 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 582 and 258 is 6
Notice that 6 = HCF(60,6) = HCF(66,60) = HCF(258,66) = HCF(582,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 6, we apply the division lemma to 21 and 6, to get
21 = 6 x 3 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 21 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) .
