HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 331, 905, 893 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 331, 905, 893 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 331, 905, 893 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 331, 905, 893 is 1.
HCF(331, 905, 893) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 331, 905, 893 is 1.
Step 1: Since 905 > 331, we apply the division lemma to 905 and 331, to get
905 = 331 x 2 + 243
Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 243 and 331, to get
331 = 243 x 1 + 88
Step 3: We consider the new divisor 243 and the new remainder 88, and apply the division lemma to get
243 = 88 x 2 + 67
We consider the new divisor 88 and the new remainder 67,and apply the division lemma to get
88 = 67 x 1 + 21
We consider the new divisor 67 and the new remainder 21,and apply the division lemma to get
67 = 21 x 3 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 331 and 905 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(67,21) = HCF(88,67) = HCF(243,88) = HCF(331,243) = HCF(905,331) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 893 > 1, we apply the division lemma to 893 and 1, to get
893 = 1 x 893 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 893 is 1
Notice that 1 = HCF(893,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
