HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 47, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 47, 905 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, 47, 905 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, 47, 905 is 1.
HCF(797, 47, 905) = 1
HCF of 797, 47, 905 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 47, 905 is 1.
Highest Common Factor of 797,47,905 is 1
Step 1: Since 797 > 47, we apply the division lemma to 797 and 47, to get
797 = 47 x 16 + 45
Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 45 and 47, to get
47 = 45 x 1 + 2
Step 3: We consider the new divisor 45 and the new remainder 2, and apply the division lemma to get
45 = 2 x 22 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 47 is 1
Notice that 1 = HCF(2,1) = HCF(45,2) = HCF(47,45) = HCF(797,47) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 905 > 1, we apply the division lemma to 905 and 1, to get
905 = 1 x 905 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 905 is 1
Notice that 1 = HCF(905,1) .
