HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 303, 855, 183 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 303, 855, 183 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 303, 855, 183 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 303, 855, 183 is 3.
HCF(303, 855, 183) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 303, 855, 183 is 3.
Step 1: Since 855 > 303, we apply the division lemma to 855 and 303, to get
855 = 303 x 2 + 249
Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 249 and 303, to get
303 = 249 x 1 + 54
Step 3: We consider the new divisor 249 and the new remainder 54, and apply the division lemma to get
249 = 54 x 4 + 33
We consider the new divisor 54 and the new remainder 33,and apply the division lemma to get
54 = 33 x 1 + 21
We consider the new divisor 33 and the new remainder 21,and apply the division lemma to get
33 = 21 x 1 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 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 303 and 855 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(54,33) = HCF(249,54) = HCF(303,249) = HCF(855,303) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 183 > 3, we apply the division lemma to 183 and 3, to get
183 = 3 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 183 is 3
Notice that 3 = HCF(183,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
