HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 48828 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 642, 48828 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 642, 48828 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 642, 48828 is 6.
HCF(642, 48828) = 6
HCF of 642, 48828 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 642, 48828 is 6.
Highest Common Factor of 642,48828 is 6
Step 1: Since 48828 > 642, we apply the division lemma to 48828 and 642, to get
48828 = 642 x 76 + 36
Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 36 and 642, to get
642 = 36 x 17 + 30
Step 3: We consider the new divisor 36 and the new remainder 30, and apply the division lemma to get
36 = 30 x 1 + 6
We consider the new divisor 30 and the new remainder 6, and apply the division lemma to get
30 = 6 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 642 and 48828 is 6
Notice that 6 = HCF(30,6) = HCF(36,30) = HCF(642,36) = HCF(48828,642) .
