HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 1238 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 330, 1238 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 330, 1238 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 330, 1238 is 2.
HCF(330, 1238) = 2
HCF of 330, 1238 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 330, 1238 is 2.
Highest Common Factor of 330,1238 is 2
Step 1: Since 1238 > 330, we apply the division lemma to 1238 and 330, to get
1238 = 330 x 3 + 248
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 248 and 330, to get
330 = 248 x 1 + 82
Step 3: We consider the new divisor 248 and the new remainder 82, and apply the division lemma to get
248 = 82 x 3 + 2
We consider the new divisor 82 and the new remainder 2, and apply the division lemma to get
82 = 2 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 330 and 1238 is 2
Notice that 2 = HCF(82,2) = HCF(248,82) = HCF(330,248) = HCF(1238,330) .
