HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 259, 383 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 259, 383 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 991, 259, 383 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 991, 259, 383 is 1.
HCF(991, 259, 383) = 1
HCF of 991, 259, 383 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 991, 259, 383 is 1.
Highest Common Factor of 991,259,383 is 1
Step 1: Since 991 > 259, we apply the division lemma to 991 and 259, to get
991 = 259 x 3 + 214
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 214 and 259, to get
259 = 214 x 1 + 45
Step 3: We consider the new divisor 214 and the new remainder 45, and apply the division lemma to get
214 = 45 x 4 + 34
We consider the new divisor 45 and the new remainder 34,and apply the division lemma to get
45 = 34 x 1 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 259 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(45,34) = HCF(214,45) = HCF(259,214) = HCF(991,259) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 383 > 1, we apply the division lemma to 383 and 1, to get
383 = 1 x 383 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 383 is 1
Notice that 1 = HCF(383,1) .
