HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 8518 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 8518 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 428, 8518 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 428, 8518 is 2.
HCF(428, 8518) = 2
HCF of 428, 8518 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 8518 is 2.
Highest Common Factor of 428,8518 is 2
Step 1: Since 8518 > 428, we apply the division lemma to 8518 and 428, to get
8518 = 428 x 19 + 386
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 386 and 428, to get
428 = 386 x 1 + 42
Step 3: We consider the new divisor 386 and the new remainder 42, and apply the division lemma to get
386 = 42 x 9 + 8
We consider the new divisor 42 and the new remainder 8,and apply the division lemma to get
42 = 8 x 5 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 428 and 8518 is 2
Notice that 2 = HCF(8,2) = HCF(42,8) = HCF(386,42) = HCF(428,386) = HCF(8518,428) .
