HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 441, 210, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 441, 210, 221 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 441, 210, 221 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 441, 210, 221 is 1.
HCF(441, 210, 221) = 1
HCF of 441, 210, 221 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 441, 210, 221 is 1.
Highest Common Factor of 441,210,221 is 1
Step 1: Since 441 > 210, we apply the division lemma to 441 and 210, to get
441 = 210 x 2 + 21
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 21 and 210, to get
210 = 21 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 441 and 210 is 21
Notice that 21 = HCF(210,21) = HCF(441,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 221 > 21, we apply the division lemma to 221 and 21, to get
221 = 21 x 10 + 11
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 11 and 21, to get
21 = 11 x 1 + 10
Step 3: We consider the new divisor 11 and the new remainder 10, and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 21 and 221 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(221,21) .
