HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 112, 306, 215, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 112, 306, 215, 805 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 112, 306, 215, 805 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 112, 306, 215, 805 is 1.
HCF(112, 306, 215, 805) = 1
HCF of 112, 306, 215, 805 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 112, 306, 215, 805 is 1.
Highest Common Factor of 112,306,215,805 is 1
Step 1: Since 306 > 112, we apply the division lemma to 306 and 112, to get
306 = 112 x 2 + 82
Step 2: Since the reminder 112 ≠ 0, we apply division lemma to 82 and 112, to get
112 = 82 x 1 + 30
Step 3: We consider the new divisor 82 and the new remainder 30, and apply the division lemma to get
82 = 30 x 2 + 22
We consider the new divisor 30 and the new remainder 22,and apply the division lemma to get
30 = 22 x 1 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 112 and 306 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(30,22) = HCF(82,30) = HCF(112,82) = HCF(306,112) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 215 > 2, we apply the division lemma to 215 and 2, to get
215 = 2 x 107 + 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 215 is 1
Notice that 1 = HCF(2,1) = HCF(215,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get
805 = 1 x 805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1
Notice that 1 = HCF(805,1) .
