HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7938, 8454 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 7938, 8454 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 7938, 8454 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 7938, 8454 is 6.
HCF(7938, 8454) = 6
HCF of 7938, 8454 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7938, 8454 is 6.
Highest Common Factor of 7938,8454 is 6
Step 1: Since 8454 > 7938, we apply the division lemma to 8454 and 7938, to get
8454 = 7938 x 1 + 516
Step 2: Since the reminder 7938 ≠ 0, we apply division lemma to 516 and 7938, to get
7938 = 516 x 15 + 198
Step 3: We consider the new divisor 516 and the new remainder 198, and apply the division lemma to get
516 = 198 x 2 + 120
We consider the new divisor 198 and the new remainder 120,and apply the division lemma to get
198 = 120 x 1 + 78
We consider the new divisor 120 and the new remainder 78,and apply the division lemma to get
120 = 78 x 1 + 42
We consider the new divisor 78 and the new remainder 42,and apply the division lemma to get
78 = 42 x 1 + 36
We consider the new divisor 42 and the new remainder 36,and apply the division lemma to get
42 = 36 x 1 + 6
We consider the new divisor 36 and the new remainder 6,and apply the division lemma to get
36 = 6 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 7938 and 8454 is 6
Notice that 6 = HCF(36,6) = HCF(42,36) = HCF(78,42) = HCF(120,78) = HCF(198,120) = HCF(516,198) = HCF(7938,516) = HCF(8454,7938) .
