HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 443, 321 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 125, 443, 321 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 125, 443, 321 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 125, 443, 321 is 1.
HCF(125, 443, 321) = 1
HCF of 125, 443, 321 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 125, 443, 321 is 1.
Highest Common Factor of 125,443,321 is 1
Step 1: Since 443 > 125, we apply the division lemma to 443 and 125, to get
443 = 125 x 3 + 68
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 68 and 125, to get
125 = 68 x 1 + 57
Step 3: We consider the new divisor 68 and the new remainder 57, and apply the division lemma to get
68 = 57 x 1 + 11
We consider the new divisor 57 and the new remainder 11,and apply the division lemma to get
57 = 11 x 5 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 125 and 443 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(57,11) = HCF(68,57) = HCF(125,68) = HCF(443,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 321 > 1, we apply the division lemma to 321 and 1, to get
321 = 1 x 321 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 321 is 1
Notice that 1 = HCF(321,1) .
