HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7539, 3921 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 7539, 3921 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 7539, 3921 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 7539, 3921 is 3.
HCF(7539, 3921) = 3
HCF of 7539, 3921 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7539, 3921 is 3.
Highest Common Factor of 7539,3921 is 3
Step 1: Since 7539 > 3921, we apply the division lemma to 7539 and 3921, to get
7539 = 3921 x 1 + 3618
Step 2: Since the reminder 3921 ≠ 0, we apply division lemma to 3618 and 3921, to get
3921 = 3618 x 1 + 303
Step 3: We consider the new divisor 3618 and the new remainder 303, and apply the division lemma to get
3618 = 303 x 11 + 285
We consider the new divisor 303 and the new remainder 285,and apply the division lemma to get
303 = 285 x 1 + 18
We consider the new divisor 285 and the new remainder 18,and apply the division lemma to get
285 = 18 x 15 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 7539 and 3921 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(285,18) = HCF(303,285) = HCF(3618,303) = HCF(3921,3618) = HCF(7539,3921) .
