HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 454, 492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 454, 492 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 797, 454, 492 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 797, 454, 492 is 1.
HCF(797, 454, 492) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 454, 492 is 1.
Step 1: Since 797 > 454, we apply the division lemma to 797 and 454, to get
797 = 454 x 1 + 343
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 343 and 454, to get
454 = 343 x 1 + 111
Step 3: We consider the new divisor 343 and the new remainder 111, and apply the division lemma to get
343 = 111 x 3 + 10
We consider the new divisor 111 and the new remainder 10,and apply the division lemma to get
111 = 10 x 11 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 454 is 1
Notice that 1 = HCF(10,1) = HCF(111,10) = HCF(343,111) = HCF(454,343) = HCF(797,454) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 492 > 1, we apply the division lemma to 492 and 1, to get
492 = 1 x 492 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 492 is 1
Notice that 1 = HCF(492,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
