HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 306, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 306, 497 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 306, 497 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 306, 497 is 1.
HCF(306, 497) = 1
HCF of 306, 497 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 306, 497 is 1.
Highest Common Factor of 306,497 is 1
Step 1: Since 497 > 306, we apply the division lemma to 497 and 306, to get
497 = 306 x 1 + 191
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 191 and 306, to get
306 = 191 x 1 + 115
Step 3: We consider the new divisor 191 and the new remainder 115, and apply the division lemma to get
191 = 115 x 1 + 76
We consider the new divisor 115 and the new remainder 76,and apply the division lemma to get
115 = 76 x 1 + 39
We consider the new divisor 76 and the new remainder 39,and apply the division lemma to get
76 = 39 x 1 + 37
We consider the new divisor 39 and the new remainder 37,and apply the division lemma to get
39 = 37 x 1 + 2
We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get
37 = 2 x 18 + 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 306 and 497 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) = HCF(76,39) = HCF(115,76) = HCF(191,115) = HCF(306,191) = HCF(497,306) .
