HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 729, 873 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 729, 873 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 556, 729, 873 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 556, 729, 873 is 1.
HCF(556, 729, 873) = 1
HCF of 556, 729, 873 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 729, 873 is 1.
Highest Common Factor of 556,729,873 is 1
Step 1: Since 729 > 556, we apply the division lemma to 729 and 556, to get
729 = 556 x 1 + 173
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 173 and 556, to get
556 = 173 x 3 + 37
Step 3: We consider the new divisor 173 and the new remainder 37, and apply the division lemma to get
173 = 37 x 4 + 25
We consider the new divisor 37 and the new remainder 25,and apply the division lemma to get
37 = 25 x 1 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 556 and 729 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(37,25) = HCF(173,37) = HCF(556,173) = HCF(729,556) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 873 > 1, we apply the division lemma to 873 and 1, to get
873 = 1 x 873 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 873 is 1
Notice that 1 = HCF(873,1) .
