HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 7978, 7254 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 7978, 7254 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 268, 7978, 7254 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 268, 7978, 7254 is 2.
HCF(268, 7978, 7254) = 2
HCF of 268, 7978, 7254 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 268, 7978, 7254 is 2.
Highest Common Factor of 268,7978,7254 is 2
Step 1: Since 7978 > 268, we apply the division lemma to 7978 and 268, to get
7978 = 268 x 29 + 206
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 206 and 268, to get
268 = 206 x 1 + 62
Step 3: We consider the new divisor 206 and the new remainder 62, and apply the division lemma to get
206 = 62 x 3 + 20
We consider the new divisor 62 and the new remainder 20,and apply the division lemma to get
62 = 20 x 3 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 268 and 7978 is 2
Notice that 2 = HCF(20,2) = HCF(62,20) = HCF(206,62) = HCF(268,206) = HCF(7978,268) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7254 > 2, we apply the division lemma to 7254 and 2, to get
7254 = 2 x 3627 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 7254 is 2
Notice that 2 = HCF(7254,2) .
