HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 495, 480 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 495, 480 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 297, 495, 480 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 297, 495, 480 is 3.
HCF(297, 495, 480) = 3
HCF of 297, 495, 480 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 495, 480 is 3.
Highest Common Factor of 297,495,480 is 3
Step 1: Since 495 > 297, we apply the division lemma to 495 and 297, to get
495 = 297 x 1 + 198
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 198 and 297, to get
297 = 198 x 1 + 99
Step 3: We consider the new divisor 198 and the new remainder 99, and apply the division lemma to get
198 = 99 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 99, the HCF of 297 and 495 is 99
Notice that 99 = HCF(198,99) = HCF(297,198) = HCF(495,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 480 > 99, we apply the division lemma to 480 and 99, to get
480 = 99 x 4 + 84
Step 2: Since the reminder 99 ≠ 0, we apply division lemma to 84 and 99, to get
99 = 84 x 1 + 15
Step 3: We consider the new divisor 84 and the new remainder 15, and apply the division lemma to get
84 = 15 x 5 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 99 and 480 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(84,15) = HCF(99,84) = HCF(480,99) .
