HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 168, 805, 796 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 168, 805, 796 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 168, 805, 796 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 168, 805, 796 is 1.
HCF(168, 805, 796) = 1
HCF of 168, 805, 796 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 168, 805, 796 is 1.
Highest Common Factor of 168,805,796 is 1
Step 1: Since 805 > 168, we apply the division lemma to 805 and 168, to get
805 = 168 x 4 + 133
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 133 and 168, to get
168 = 133 x 1 + 35
Step 3: We consider the new divisor 133 and the new remainder 35, and apply the division lemma to get
133 = 35 x 3 + 28
We consider the new divisor 35 and the new remainder 28,and apply the division lemma to get
35 = 28 x 1 + 7
We consider the new divisor 28 and the new remainder 7,and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 168 and 805 is 7
Notice that 7 = HCF(28,7) = HCF(35,28) = HCF(133,35) = HCF(168,133) = HCF(805,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 796 > 7, we apply the division lemma to 796 and 7, to get
796 = 7 x 113 + 5
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 5 and 7, to get
7 = 5 x 1 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 7 and 796 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(796,7) .
