HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 59, 309, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 30, 59, 309, 231 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 30, 59, 309, 231 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 30, 59, 309, 231 is 1.
HCF(30, 59, 309, 231) = 1
HCF of 30, 59, 309, 231 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 30, 59, 309, 231 is 1.
Highest Common Factor of 30,59,309,231 is 1
Step 1: Since 59 > 30, we apply the division lemma to 59 and 30, to get
59 = 30 x 1 + 29
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 29 and 30, to get
30 = 29 x 1 + 1
Step 3: We consider the new divisor 29 and the new remainder 1, and apply the division lemma to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 30 and 59 is 1
Notice that 1 = HCF(29,1) = HCF(30,29) = HCF(59,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get
309 = 1 x 309 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1
Notice that 1 = HCF(309,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 231 > 1, we apply the division lemma to 231 and 1, to get
231 = 1 x 231 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 231 is 1
Notice that 1 = HCF(231,1) .
