HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 97299 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 97299 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 291, 97299 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 291, 97299 is 3.
HCF(291, 97299) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 97299 is 3.
Step 1: Since 97299 > 291, we apply the division lemma to 97299 and 291, to get
97299 = 291 x 334 + 105
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 105 and 291, to get
291 = 105 x 2 + 81
Step 3: We consider the new divisor 105 and the new remainder 81, and apply the division lemma to get
105 = 81 x 1 + 24
We consider the new divisor 81 and the new remainder 24,and apply the division lemma to get
81 = 24 x 3 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 291 and 97299 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(81,24) = HCF(105,81) = HCF(291,105) = HCF(97299,291) .
Here are some samples of HCF using Euclid's Algorithm calculations.
