HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 306, 291 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 633, 306, 291 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 633, 306, 291 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 633, 306, 291 is 3.
HCF(633, 306, 291) = 3
HCF of 633, 306, 291 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 633, 306, 291 is 3.
Highest Common Factor of 633,306,291 is 3
Step 1: Since 633 > 306, we apply the division lemma to 633 and 306, to get
633 = 306 x 2 + 21
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 21 and 306, to get
306 = 21 x 14 + 12
Step 3: 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 633 and 306 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(306,21) = HCF(633,306) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 291 > 3, we apply the division lemma to 291 and 3, to get
291 = 3 x 97 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 291 is 3
Notice that 3 = HCF(291,3) .
