HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 520, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 520, 443 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 841, 520, 443 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 841, 520, 443 is 1.
HCF(841, 520, 443) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 520, 443 is 1.
Step 1: Since 841 > 520, we apply the division lemma to 841 and 520, to get
841 = 520 x 1 + 321
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 321 and 520, to get
520 = 321 x 1 + 199
Step 3: We consider the new divisor 321 and the new remainder 199, and apply the division lemma to get
321 = 199 x 1 + 122
We consider the new divisor 199 and the new remainder 122,and apply the division lemma to get
199 = 122 x 1 + 77
We consider the new divisor 122 and the new remainder 77,and apply the division lemma to get
122 = 77 x 1 + 45
We consider the new divisor 77 and the new remainder 45,and apply the division lemma to get
77 = 45 x 1 + 32
We consider the new divisor 45 and the new remainder 32,and apply the division lemma to get
45 = 32 x 1 + 13
We consider the new divisor 32 and the new remainder 13,and apply the division lemma to get
32 = 13 x 2 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 520 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(32,13) = HCF(45,32) = HCF(77,45) = HCF(122,77) = HCF(199,122) = HCF(321,199) = HCF(520,321) = HCF(841,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 1, we apply the division lemma to 443 and 1, to get
443 = 1 x 443 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 443 is 1
Notice that 1 = HCF(443,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
