HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 195, 801 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 195, 801 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 531, 195, 801 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 531, 195, 801 is 3.
HCF(531, 195, 801) = 3
HCF of 531, 195, 801 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 195, 801 is 3.
Highest Common Factor of 531,195,801 is 3
Step 1: Since 531 > 195, we apply the division lemma to 531 and 195, to get
531 = 195 x 2 + 141
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 141 and 195, to get
195 = 141 x 1 + 54
Step 3: We consider the new divisor 141 and the new remainder 54, and apply the division lemma to get
141 = 54 x 2 + 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 531 and 195 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(54,33) = HCF(141,54) = HCF(195,141) = HCF(531,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 801 > 3, we apply the division lemma to 801 and 3, to get
801 = 3 x 267 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 801 is 3
Notice that 3 = HCF(801,3) .
