HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 810, 458 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 810, 458 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 531, 810, 458 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 531, 810, 458 is 1.
HCF(531, 810, 458) = 1
HCF of 531, 810, 458 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 810, 458 is 1.
Highest Common Factor of 531,810,458 is 1
Step 1: Since 810 > 531, we apply the division lemma to 810 and 531, to get
810 = 531 x 1 + 279
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 279 and 531, to get
531 = 279 x 1 + 252
Step 3: We consider the new divisor 279 and the new remainder 252, and apply the division lemma to get
279 = 252 x 1 + 27
We consider the new divisor 252 and the new remainder 27,and apply the division lemma to get
252 = 27 x 9 + 9
We consider the new divisor 27 and the new remainder 9,and apply the division lemma to get
27 = 9 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 531 and 810 is 9
Notice that 9 = HCF(27,9) = HCF(252,27) = HCF(279,252) = HCF(531,279) = HCF(810,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 458 > 9, we apply the division lemma to 458 and 9, to get
458 = 9 x 50 + 8
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 8 and 9, to get
9 = 8 x 1 + 1
Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 458 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(458,9) .
