HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1491, 9543 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1491, 9543 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 1491, 9543 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 1491, 9543 is 3.
HCF(1491, 9543) = 3
HCF of 1491, 9543 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1491, 9543 is 3.
Highest Common Factor of 1491,9543 is 3
Step 1: Since 9543 > 1491, we apply the division lemma to 9543 and 1491, to get
9543 = 1491 x 6 + 597
Step 2: Since the reminder 1491 ≠ 0, we apply division lemma to 597 and 1491, to get
1491 = 597 x 2 + 297
Step 3: We consider the new divisor 597 and the new remainder 297, and apply the division lemma to get
597 = 297 x 2 + 3
We consider the new divisor 297 and the new remainder 3, and apply the division lemma to get
297 = 3 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 1491 and 9543 is 3
Notice that 3 = HCF(297,3) = HCF(597,297) = HCF(1491,597) = HCF(9543,1491) .
