HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 799, 172, 800 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 799, 172, 800 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 799, 172, 800 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 799, 172, 800 is 1.
HCF(799, 172, 800) = 1
HCF of 799, 172, 800 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 799, 172, 800 is 1.
Highest Common Factor of 799,172,800 is 1
Step 1: Since 799 > 172, we apply the division lemma to 799 and 172, to get
799 = 172 x 4 + 111
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 111 and 172, to get
172 = 111 x 1 + 61
Step 3: We consider the new divisor 111 and the new remainder 61, and apply the division lemma to get
111 = 61 x 1 + 50
We consider the new divisor 61 and the new remainder 50,and apply the division lemma to get
61 = 50 x 1 + 11
We consider the new divisor 50 and the new remainder 11,and apply the division lemma to get
50 = 11 x 4 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 799 and 172 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(50,11) = HCF(61,50) = HCF(111,61) = HCF(172,111) = HCF(799,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 800 > 1, we apply the division lemma to 800 and 1, to get
800 = 1 x 800 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 800 is 1
Notice that 1 = HCF(800,1) .
