HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 715, 299 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 715, 299 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 458, 715, 299 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 458, 715, 299 is 1.
HCF(458, 715, 299) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 458, 715, 299 is 1.
Step 1: Since 715 > 458, we apply the division lemma to 715 and 458, to get
715 = 458 x 1 + 257
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 257 and 458, to get
458 = 257 x 1 + 201
Step 3: We consider the new divisor 257 and the new remainder 201, and apply the division lemma to get
257 = 201 x 1 + 56
We consider the new divisor 201 and the new remainder 56,and apply the division lemma to get
201 = 56 x 3 + 33
We consider the new divisor 56 and the new remainder 33,and apply the division lemma to get
56 = 33 x 1 + 23
We consider the new divisor 33 and the new remainder 23,and apply the division lemma to get
33 = 23 x 1 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 458 and 715 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(33,23) = HCF(56,33) = HCF(201,56) = HCF(257,201) = HCF(458,257) = HCF(715,458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 299 > 1, we apply the division lemma to 299 and 1, to get
299 = 1 x 299 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 299 is 1
Notice that 1 = HCF(299,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
