HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1282, 7938 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 1282, 7938 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 1282, 7938 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 1282, 7938 is 2.
HCF(1282, 7938) = 2
HCF of 1282, 7938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1282, 7938 is 2.
Highest Common Factor of 1282,7938 is 2
Step 1: Since 7938 > 1282, we apply the division lemma to 7938 and 1282, to get
7938 = 1282 x 6 + 246
Step 2: Since the reminder 1282 ≠ 0, we apply division lemma to 246 and 1282, to get
1282 = 246 x 5 + 52
Step 3: We consider the new divisor 246 and the new remainder 52, and apply the division lemma to get
246 = 52 x 4 + 38
We consider the new divisor 52 and the new remainder 38,and apply the division lemma to get
52 = 38 x 1 + 14
We consider the new divisor 38 and the new remainder 14,and apply the division lemma to get
38 = 14 x 2 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1282 and 7938 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(38,14) = HCF(52,38) = HCF(246,52) = HCF(1282,246) = HCF(7938,1282) .
