HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 810 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 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 497, 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 497, 810 is 1.
HCF(497, 810) = 1
HCF of 497, 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 497, 810 is 1.
Highest Common Factor of 497,810 is 1
Step 1: Since 810 > 497, we apply the division lemma to 810 and 497, to get
810 = 497 x 1 + 313
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 313 and 497, to get
497 = 313 x 1 + 184
Step 3: We consider the new divisor 313 and the new remainder 184, and apply the division lemma to get
313 = 184 x 1 + 129
We consider the new divisor 184 and the new remainder 129,and apply the division lemma to get
184 = 129 x 1 + 55
We consider the new divisor 129 and the new remainder 55,and apply the division lemma to get
129 = 55 x 2 + 19
We consider the new divisor 55 and the new remainder 19,and apply the division lemma to get
55 = 19 x 2 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 497 and 810 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(55,19) = HCF(129,55) = HCF(184,129) = HCF(313,184) = HCF(497,313) = HCF(810,497) .
