HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 230, 122 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 521, 230, 122 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 521, 230, 122 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 521, 230, 122 is 1.
HCF(521, 230, 122) = 1
HCF of 521, 230, 122 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 521, 230, 122 is 1.
Highest Common Factor of 521,230,122 is 1
Step 1: Since 521 > 230, we apply the division lemma to 521 and 230, to get
521 = 230 x 2 + 61
Step 2: Since the reminder 230 ≠ 0, we apply division lemma to 61 and 230, to get
230 = 61 x 3 + 47
Step 3: We consider the new divisor 61 and the new remainder 47, and apply the division lemma to get
61 = 47 x 1 + 14
We consider the new divisor 47 and the new remainder 14,and apply the division lemma to get
47 = 14 x 3 + 5
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 521 and 230 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(47,14) = HCF(61,47) = HCF(230,61) = HCF(521,230) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 122 > 1, we apply the division lemma to 122 and 1, to get
122 = 1 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 122 is 1
Notice that 1 = HCF(122,1) .
