HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 967, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 967, 181 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 798, 967, 181 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 798, 967, 181 is 1.
HCF(798, 967, 181) = 1
HCF of 798, 967, 181 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 798, 967, 181 is 1.
Highest Common Factor of 798,967,181 is 1
Step 1: Since 967 > 798, we apply the division lemma to 967 and 798, to get
967 = 798 x 1 + 169
Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 169 and 798, to get
798 = 169 x 4 + 122
Step 3: We consider the new divisor 169 and the new remainder 122, and apply the division lemma to get
169 = 122 x 1 + 47
We consider the new divisor 122 and the new remainder 47,and apply the division lemma to get
122 = 47 x 2 + 28
We consider the new divisor 47 and the new remainder 28,and apply the division lemma to get
47 = 28 x 1 + 19
We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get
28 = 19 x 1 + 9
We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 798 and 967 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(47,28) = HCF(122,47) = HCF(169,122) = HCF(798,169) = HCF(967,798) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 1, we apply the division lemma to 181 and 1, to get
181 = 1 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1
Notice that 1 = HCF(181,1) .
