HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 507, 33 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 507, 33 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 801, 507, 33 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 801, 507, 33 is 3.
HCF(801, 507, 33) = 3
HCF of 801, 507, 33 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 507, 33 is 3.
Highest Common Factor of 801,507,33 is 3
Step 1: Since 801 > 507, we apply the division lemma to 801 and 507, to get
801 = 507 x 1 + 294
Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 294 and 507, to get
507 = 294 x 1 + 213
Step 3: We consider the new divisor 294 and the new remainder 213, and apply the division lemma to get
294 = 213 x 1 + 81
We consider the new divisor 213 and the new remainder 81,and apply the division lemma to get
213 = 81 x 2 + 51
We consider the new divisor 81 and the new remainder 51,and apply the division lemma to get
81 = 51 x 1 + 30
We consider the new divisor 51 and the new remainder 30,and apply the division lemma to get
51 = 30 x 1 + 21
We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get
30 = 21 x 1 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 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 801 and 507 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(51,30) = HCF(81,51) = HCF(213,81) = HCF(294,213) = HCF(507,294) = HCF(801,507) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 33 > 3, we apply the division lemma to 33 and 3, to get
33 = 3 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 33 is 3
Notice that 3 = HCF(33,3) .
