HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 261, 810 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 261, 810 is 1 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 493, 261, 810 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 493, 261, 810 is 1.
HCF(493, 261, 810) = 1
HCF of 493, 261, 810 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 261, 810 is 1.
Highest Common Factor of 493,261,810 is 1
Step 1: Since 493 > 261, we apply the division lemma to 493 and 261, to get
493 = 261 x 1 + 232
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 232 and 261, to get
261 = 232 x 1 + 29
Step 3: We consider the new divisor 232 and the new remainder 29, and apply the division lemma to get
232 = 29 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 493 and 261 is 29
Notice that 29 = HCF(232,29) = HCF(261,232) = HCF(493,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 810 > 29, we apply the division lemma to 810 and 29, to get
810 = 29 x 27 + 27
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 27 and 29, to get
29 = 27 x 1 + 2
Step 3: We consider the new divisor 27 and the new remainder 2, and apply the division lemma to get
27 = 2 x 13 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 29 and 810 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(29,27) = HCF(810,29) .
