HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 937, 342 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 937, 342 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, 937, 342 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, 937, 342 is 1.
HCF(479, 937, 342) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 937, 342 is 1.
Step 1: Since 937 > 479, we apply the division lemma to 937 and 479, to get
937 = 479 x 1 + 458
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 458 and 479, to get
479 = 458 x 1 + 21
Step 3: We consider the new divisor 458 and the new remainder 21, and apply the division lemma to get
458 = 21 x 21 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 937 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(458,21) = HCF(479,458) = HCF(937,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 342 > 1, we apply the division lemma to 342 and 1, to get
342 = 1 x 342 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 342 is 1
Notice that 1 = HCF(342,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
