HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 523, 390, 83 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 523, 390, 83 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 231, 523, 390, 83 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 231, 523, 390, 83 is 1.
HCF(231, 523, 390, 83) = 1
HCF of 231, 523, 390, 83 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 523, 390, 83 is 1.
Highest Common Factor of 231,523,390,83 is 1
Step 1: Since 523 > 231, we apply the division lemma to 523 and 231, to get
523 = 231 x 2 + 61
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 61 and 231, to get
231 = 61 x 3 + 48
Step 3: We consider the new divisor 61 and the new remainder 48, and apply the division lemma to get
61 = 48 x 1 + 13
We consider the new divisor 48 and the new remainder 13,and apply the division lemma to get
48 = 13 x 3 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 231 and 523 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(48,13) = HCF(61,48) = HCF(231,61) = HCF(523,231) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get
390 = 1 x 390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1
Notice that 1 = HCF(390,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 83 > 1, we apply the division lemma to 83 and 1, to get
83 = 1 x 83 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 83 is 1
Notice that 1 = HCF(83,1) .
