HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 7915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 7915 is 1 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 297, 7915 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 297, 7915 is 1.
HCF(297, 7915) = 1
HCF of 297, 7915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 7915 is 1.
Highest Common Factor of 297,7915 is 1
Step 1: Since 7915 > 297, we apply the division lemma to 7915 and 297, to get
7915 = 297 x 26 + 193
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 193 and 297, to get
297 = 193 x 1 + 104
Step 3: We consider the new divisor 193 and the new remainder 104, and apply the division lemma to get
193 = 104 x 1 + 89
We consider the new divisor 104 and the new remainder 89,and apply the division lemma to get
104 = 89 x 1 + 15
We consider the new divisor 89 and the new remainder 15,and apply the division lemma to get
89 = 15 x 5 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 297 and 7915 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(89,15) = HCF(104,89) = HCF(193,104) = HCF(297,193) = HCF(7915,297) .
