HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 811, 380 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 811, 380 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, 811, 380 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, 811, 380 is 1.
HCF(531, 811, 380) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 811, 380 is 1.
Step 1: Since 811 > 531, we apply the division lemma to 811 and 531, to get
811 = 531 x 1 + 280
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 280 and 531, to get
531 = 280 x 1 + 251
Step 3: We consider the new divisor 280 and the new remainder 251, and apply the division lemma to get
280 = 251 x 1 + 29
We consider the new divisor 251 and the new remainder 29,and apply the division lemma to get
251 = 29 x 8 + 19
We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get
29 = 19 x 1 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 531 and 811 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(251,29) = HCF(280,251) = HCF(531,280) = HCF(811,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 380 > 1, we apply the division lemma to 380 and 1, to get
380 = 1 x 380 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 380 is 1
Notice that 1 = HCF(380,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
