HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 463, 721, 937 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 463, 721, 937 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 463, 721, 937 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 463, 721, 937 is 1.
HCF(463, 721, 937) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 463, 721, 937 is 1.
Step 1: Since 721 > 463, we apply the division lemma to 721 and 463, to get
721 = 463 x 1 + 258
Step 2: Since the reminder 463 ≠ 0, we apply division lemma to 258 and 463, to get
463 = 258 x 1 + 205
Step 3: We consider the new divisor 258 and the new remainder 205, and apply the division lemma to get
258 = 205 x 1 + 53
We consider the new divisor 205 and the new remainder 53,and apply the division lemma to get
205 = 53 x 3 + 46
We consider the new divisor 53 and the new remainder 46,and apply the division lemma to get
53 = 46 x 1 + 7
We consider the new divisor 46 and the new remainder 7,and apply the division lemma to get
46 = 7 x 6 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 463 and 721 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(46,7) = HCF(53,46) = HCF(205,53) = HCF(258,205) = HCF(463,258) = HCF(721,463) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 937 > 1, we apply the division lemma to 937 and 1, to get
937 = 1 x 937 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 937 is 1
Notice that 1 = HCF(937,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
