HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 890, 311 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 890, 311 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, 890, 311 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, 890, 311 is 1.
HCF(991, 890, 311) = 1
HCF of 991, 890, 311 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, 890, 311 is 1.
Highest Common Factor of 991,890,311 is 1
Step 1: Since 991 > 890, we apply the division lemma to 991 and 890, to get
991 = 890 x 1 + 101
Step 2: Since the reminder 890 ≠ 0, we apply division lemma to 101 and 890, to get
890 = 101 x 8 + 82
Step 3: We consider the new divisor 101 and the new remainder 82, and apply the division lemma to get
101 = 82 x 1 + 19
We consider the new divisor 82 and the new remainder 19,and apply the division lemma to get
82 = 19 x 4 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 890 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(82,19) = HCF(101,82) = HCF(890,101) = HCF(991,890) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 311 > 1, we apply the division lemma to 311 and 1, to get
311 = 1 x 311 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 311 is 1
Notice that 1 = HCF(311,1) .
