HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 529, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 529, 457 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 730, 529, 457 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 730, 529, 457 is 1.
HCF(730, 529, 457) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 529, 457 is 1.
Step 1: Since 730 > 529, we apply the division lemma to 730 and 529, to get
730 = 529 x 1 + 201
Step 2: Since the reminder 529 ≠ 0, we apply division lemma to 201 and 529, to get
529 = 201 x 2 + 127
Step 3: We consider the new divisor 201 and the new remainder 127, and apply the division lemma to get
201 = 127 x 1 + 74
We consider the new divisor 127 and the new remainder 74,and apply the division lemma to get
127 = 74 x 1 + 53
We consider the new divisor 74 and the new remainder 53,and apply the division lemma to get
74 = 53 x 1 + 21
We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get
53 = 21 x 2 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 730 and 529 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(74,53) = HCF(127,74) = HCF(201,127) = HCF(529,201) = HCF(730,529) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get
457 = 1 x 457 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1
Notice that 1 = HCF(457,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
