HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 331, 540 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 331, 540 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, 540 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, 540 is 1.
HCF(331, 540) = 1
HCF of 331, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 331, 540 is 1.
Highest Common Factor of 331,540 is 1
Step 1: Since 540 > 331, we apply the division lemma to 540 and 331, to get
540 = 331 x 1 + 209
Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 209 and 331, to get
331 = 209 x 1 + 122
Step 3: We consider the new divisor 209 and the new remainder 122, and apply the division lemma to get
209 = 122 x 1 + 87
We consider the new divisor 122 and the new remainder 87,and apply the division lemma to get
122 = 87 x 1 + 35
We consider the new divisor 87 and the new remainder 35,and apply the division lemma to get
87 = 35 x 2 + 17
We consider the new divisor 35 and the new remainder 17,and apply the division lemma to get
35 = 17 x 2 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 331 and 540 is 1
Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(87,35) = HCF(122,87) = HCF(209,122) = HCF(331,209) = HCF(540,331) .
