HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 825, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 825, 818 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 479, 825, 818 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 479, 825, 818 is 1.
HCF(479, 825, 818) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 825, 818 is 1.
Step 1: Since 825 > 479, we apply the division lemma to 825 and 479, to get
825 = 479 x 1 + 346
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 346 and 479, to get
479 = 346 x 1 + 133
Step 3: We consider the new divisor 346 and the new remainder 133, and apply the division lemma to get
346 = 133 x 2 + 80
We consider the new divisor 133 and the new remainder 80,and apply the division lemma to get
133 = 80 x 1 + 53
We consider the new divisor 80 and the new remainder 53,and apply the division lemma to get
80 = 53 x 1 + 27
We consider the new divisor 53 and the new remainder 27,and apply the division lemma to get
53 = 27 x 1 + 26
We consider the new divisor 27 and the new remainder 26,and apply the division lemma to get
27 = 26 x 1 + 1
We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 825 is 1
Notice that 1 = HCF(26,1) = HCF(27,26) = HCF(53,27) = HCF(80,53) = HCF(133,80) = HCF(346,133) = HCF(479,346) = HCF(825,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 1, we apply the division lemma to 818 and 1, to get
818 = 1 x 818 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 818 is 1
Notice that 1 = HCF(818,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
