HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 531 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 330, 531 is 3 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 330, 531 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 330, 531 is 3.
HCF(330, 531) = 3
HCF of 330, 531 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 330, 531 is 3.
Highest Common Factor of 330,531 is 3
Step 1: Since 531 > 330, we apply the division lemma to 531 and 330, to get
531 = 330 x 1 + 201
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 201 and 330, to get
330 = 201 x 1 + 129
Step 3: We consider the new divisor 201 and the new remainder 129, and apply the division lemma to get
201 = 129 x 1 + 72
We consider the new divisor 129 and the new remainder 72,and apply the division lemma to get
129 = 72 x 1 + 57
We consider the new divisor 72 and the new remainder 57,and apply the division lemma to get
72 = 57 x 1 + 15
We consider the new divisor 57 and the new remainder 15,and apply the division lemma to get
57 = 15 x 3 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 330 and 531 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(57,15) = HCF(72,57) = HCF(129,72) = HCF(201,129) = HCF(330,201) = HCF(531,330) .
