HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 585, 131 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 585, 131 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 819, 585, 131 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 819, 585, 131 is 1.
HCF(819, 585, 131) = 1
HCF of 819, 585, 131 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 585, 131 is 1.
Highest Common Factor of 819,585,131 is 1
Step 1: Since 819 > 585, we apply the division lemma to 819 and 585, to get
819 = 585 x 1 + 234
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 234 and 585, to get
585 = 234 x 2 + 117
Step 3: We consider the new divisor 234 and the new remainder 117, and apply the division lemma to get
234 = 117 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 117, the HCF of 819 and 585 is 117
Notice that 117 = HCF(234,117) = HCF(585,234) = HCF(819,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 131 > 117, we apply the division lemma to 131 and 117, to get
131 = 117 x 1 + 14
Step 2: Since the reminder 117 ≠ 0, we apply division lemma to 14 and 117, to get
117 = 14 x 8 + 5
Step 3: We consider the new divisor 14 and the new remainder 5, and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 117 and 131 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(117,14) = HCF(131,117) .
