HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 258, 765 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 258, 765 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 258, 765 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 258, 765 is 3.
HCF(258, 765) = 3
HCF of 258, 765 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 258, 765 is 3.
Highest Common Factor of 258,765 is 3
Step 1: Since 765 > 258, we apply the division lemma to 765 and 258, to get
765 = 258 x 2 + 249
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 249 and 258, to get
258 = 249 x 1 + 9
Step 3: We consider the new divisor 249 and the new remainder 9, and apply the division lemma to get
249 = 9 x 27 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma 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 258 and 765 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(249,9) = HCF(258,249) = HCF(765,258) .
