HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 549, 56 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 389, 549, 56 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 389, 549, 56 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 389, 549, 56 is 1.
HCF(389, 549, 56) = 1
HCF of 389, 549, 56 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 389, 549, 56 is 1.
Highest Common Factor of 389,549,56 is 1
Step 1: Since 549 > 389, we apply the division lemma to 549 and 389, to get
549 = 389 x 1 + 160
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 160 and 389, to get
389 = 160 x 2 + 69
Step 3: We consider the new divisor 160 and the new remainder 69, and apply the division lemma to get
160 = 69 x 2 + 22
We consider the new divisor 69 and the new remainder 22,and apply the division lemma to get
69 = 22 x 3 + 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 389 and 549 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(69,22) = HCF(160,69) = HCF(389,160) = HCF(549,389) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 56 > 1, we apply the division lemma to 56 and 1, to get
56 = 1 x 56 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 56 is 1
Notice that 1 = HCF(56,1) .
