HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 678, 13230 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 678, 13230 is 6 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 678, 13230 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 678, 13230 is 6.
HCF(678, 13230) = 6
HCF of 678, 13230 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 678, 13230 is 6.
Highest Common Factor of 678,13230 is 6
Step 1: Since 13230 > 678, we apply the division lemma to 13230 and 678, to get
13230 = 678 x 19 + 348
Step 2: Since the reminder 678 ≠ 0, we apply division lemma to 348 and 678, to get
678 = 348 x 1 + 330
Step 3: We consider the new divisor 348 and the new remainder 330, and apply the division lemma to get
348 = 330 x 1 + 18
We consider the new divisor 330 and the new remainder 18,and apply the division lemma to get
330 = 18 x 18 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 678 and 13230 is 6
Notice that 6 = HCF(18,6) = HCF(330,18) = HCF(348,330) = HCF(678,348) = HCF(13230,678) .
