HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6438, 1268 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 6438, 1268 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 6438, 1268 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 6438, 1268 is 2.
HCF(6438, 1268) = 2
HCF of 6438, 1268 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6438, 1268 is 2.
Highest Common Factor of 6438,1268 is 2
Step 1: Since 6438 > 1268, we apply the division lemma to 6438 and 1268, to get
6438 = 1268 x 5 + 98
Step 2: Since the reminder 1268 ≠ 0, we apply division lemma to 98 and 1268, to get
1268 = 98 x 12 + 92
Step 3: We consider the new divisor 98 and the new remainder 92, and apply the division lemma to get
98 = 92 x 1 + 6
We consider the new divisor 92 and the new remainder 6,and apply the division lemma to get
92 = 6 x 15 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6438 and 1268 is 2
Notice that 2 = HCF(6,2) = HCF(92,6) = HCF(98,92) = HCF(1268,98) = HCF(6438,1268) .
