HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 72, 479, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 72, 479, 386 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 72, 479, 386 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 72, 479, 386 is 1.
HCF(72, 479, 386) = 1
HCF of 72, 479, 386 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 72, 479, 386 is 1.
Highest Common Factor of 72,479,386 is 1
Step 1: Since 479 > 72, we apply the division lemma to 479 and 72, to get
479 = 72 x 6 + 47
Step 2: Since the reminder 72 ≠ 0, we apply division lemma to 47 and 72, to get
72 = 47 x 1 + 25
Step 3: We consider the new divisor 47 and the new remainder 25, and apply the division lemma to get
47 = 25 x 1 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 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 72 and 479 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(47,25) = HCF(72,47) = HCF(479,72) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get
386 = 1 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1
Notice that 1 = HCF(386,1) .
