HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 423, 873 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 177, 423, 873 is 3 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 177, 423, 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 177, 423, 873 is 3.
HCF(177, 423, 873) = 3
HCF of 177, 423, 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 177, 423, 873 is 3.
Highest Common Factor of 177,423,873 is 3
Step 1: Since 423 > 177, we apply the division lemma to 423 and 177, to get
423 = 177 x 2 + 69
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 69 and 177, to get
177 = 69 x 2 + 39
Step 3: We consider the new divisor 69 and the new remainder 39, and apply the division lemma to get
69 = 39 x 1 + 30
We consider the new divisor 39 and the new remainder 30,and apply the division lemma to get
39 = 30 x 1 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 177 and 423 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(39,30) = HCF(69,39) = HCF(177,69) = HCF(423,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 873 > 3, we apply the division lemma to 873 and 3, to get
873 = 3 x 291 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 873 is 3
Notice that 3 = HCF(873,3) .
