HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 306, 812, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 306, 812, 173 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 306, 812, 173 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 306, 812, 173 is 1.
HCF(306, 812, 173) = 1
HCF of 306, 812, 173 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 306, 812, 173 is 1.
Highest Common Factor of 306,812,173 is 1
Step 1: Since 812 > 306, we apply the division lemma to 812 and 306, to get
812 = 306 x 2 + 200
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 200 and 306, to get
306 = 200 x 1 + 106
Step 3: We consider the new divisor 200 and the new remainder 106, and apply the division lemma to get
200 = 106 x 1 + 94
We consider the new divisor 106 and the new remainder 94,and apply the division lemma to get
106 = 94 x 1 + 12
We consider the new divisor 94 and the new remainder 12,and apply the division lemma to get
94 = 12 x 7 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 306 and 812 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(94,12) = HCF(106,94) = HCF(200,106) = HCF(306,200) = HCF(812,306) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 173 > 2, we apply the division lemma to 173 and 2, to get
173 = 2 x 86 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 173 is 1
Notice that 1 = HCF(2,1) = HCF(173,2) .
