HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8025, 3978 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 8025, 3978 is 3 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 8025, 3978 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 8025, 3978 is 3.
HCF(8025, 3978) = 3
HCF of 8025, 3978 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8025, 3978 is 3.
Highest Common Factor of 8025,3978 is 3
Step 1: Since 8025 > 3978, we apply the division lemma to 8025 and 3978, to get
8025 = 3978 x 2 + 69
Step 2: Since the reminder 3978 ≠ 0, we apply division lemma to 69 and 3978, to get
3978 = 69 x 57 + 45
Step 3: We consider the new divisor 69 and the new remainder 45, and apply the division lemma to get
69 = 45 x 1 + 24
We consider the new divisor 45 and the new remainder 24,and apply the division lemma to get
45 = 24 x 1 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 8025 and 3978 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(45,24) = HCF(69,45) = HCF(3978,69) = HCF(8025,3978) .
