HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 268 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 268 is 2 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 486, 268 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 486, 268 is 2.
HCF(486, 268) = 2
HCF of 486, 268 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 268 is 2.
Highest Common Factor of 486,268 is 2
Step 1: Since 486 > 268, we apply the division lemma to 486 and 268, to get
486 = 268 x 1 + 218
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 218 and 268, to get
268 = 218 x 1 + 50
Step 3: We consider the new divisor 218 and the new remainder 50, and apply the division lemma to get
218 = 50 x 4 + 18
We consider the new divisor 50 and the new remainder 18,and apply the division lemma to get
50 = 18 x 2 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 486 and 268 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(50,18) = HCF(218,50) = HCF(268,218) = HCF(486,268) .
