HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 31, 141, 331, 994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 31, 141, 331, 994 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 31, 141, 331, 994 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 31, 141, 331, 994 is 1.
HCF(31, 141, 331, 994) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 31, 141, 331, 994 is 1.
Step 1: Since 141 > 31, we apply the division lemma to 141 and 31, to get
141 = 31 x 4 + 17
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 17 and 31, to get
31 = 17 x 1 + 14
Step 3: We consider the new divisor 17 and the new remainder 14, and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 31 and 141 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(31,17) = HCF(141,31) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 331 > 1, we apply the division lemma to 331 and 1, to get
331 = 1 x 331 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 331 is 1
Notice that 1 = HCF(331,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 994 > 1, we apply the division lemma to 994 and 1, to get
994 = 1 x 994 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 994 is 1
Notice that 1 = HCF(994,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
