HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 6956, 9411 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 6956, 9411 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, 6956, 9411 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, 6956, 9411 is 1.
HCF(297, 6956, 9411) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 6956, 9411 is 1.
Step 1: Since 6956 > 297, we apply the division lemma to 6956 and 297, to get
6956 = 297 x 23 + 125
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 125 and 297, to get
297 = 125 x 2 + 47
Step 3: We consider the new divisor 125 and the new remainder 47, and apply the division lemma to get
125 = 47 x 2 + 31
We consider the new divisor 47 and the new remainder 31,and apply the division lemma to get
47 = 31 x 1 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 297 and 6956 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(47,31) = HCF(125,47) = HCF(297,125) = HCF(6956,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9411 > 1, we apply the division lemma to 9411 and 1, to get
9411 = 1 x 9411 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9411 is 1
Notice that 1 = HCF(9411,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
