HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 663, 537 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 663, 537 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 240, 663, 537 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 240, 663, 537 is 3.
HCF(240, 663, 537) = 3
HCF of 240, 663, 537 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 663, 537 is 3.
Highest Common Factor of 240,663,537 is 3
Step 1: Since 663 > 240, we apply the division lemma to 663 and 240, to get
663 = 240 x 2 + 183
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 183 and 240, to get
240 = 183 x 1 + 57
Step 3: We consider the new divisor 183 and the new remainder 57, and apply the division lemma to get
183 = 57 x 3 + 12
We consider the new divisor 57 and the new remainder 12,and apply the division lemma to get
57 = 12 x 4 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 240 and 663 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(57,12) = HCF(183,57) = HCF(240,183) = HCF(663,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 537 > 3, we apply the division lemma to 537 and 3, to get
537 = 3 x 179 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 537 is 3
Notice that 3 = HCF(537,3) .
