HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 719, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 719, 451 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 812, 719, 451 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 812, 719, 451 is 1.
HCF(812, 719, 451) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 719, 451 is 1.
Step 1: Since 812 > 719, we apply the division lemma to 812 and 719, to get
812 = 719 x 1 + 93
Step 2: Since the reminder 719 ≠ 0, we apply division lemma to 93 and 719, to get
719 = 93 x 7 + 68
Step 3: We consider the new divisor 93 and the new remainder 68, and apply the division lemma to get
93 = 68 x 1 + 25
We consider the new divisor 68 and the new remainder 25,and apply the division lemma to get
68 = 25 x 2 + 18
We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get
25 = 18 x 1 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 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 812 and 719 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(68,25) = HCF(93,68) = HCF(719,93) = HCF(812,719) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 451 > 1, we apply the division lemma to 451 and 1, to get
451 = 1 x 451 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 451 is 1
Notice that 1 = HCF(451,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
