HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 455, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 844, 455, 503 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 844, 455, 503 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 844, 455, 503 is 1.
HCF(844, 455, 503) = 1
HCF of 844, 455, 503 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 844, 455, 503 is 1.
Highest Common Factor of 844,455,503 is 1
Step 1: Since 844 > 455, we apply the division lemma to 844 and 455, to get
844 = 455 x 1 + 389
Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 389 and 455, to get
455 = 389 x 1 + 66
Step 3: We consider the new divisor 389 and the new remainder 66, and apply the division lemma to get
389 = 66 x 5 + 59
We consider the new divisor 66 and the new remainder 59,and apply the division lemma to get
66 = 59 x 1 + 7
We consider the new divisor 59 and the new remainder 7,and apply the division lemma to get
59 = 7 x 8 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 844 and 455 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(59,7) = HCF(66,59) = HCF(389,66) = HCF(455,389) = HCF(844,455) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get
503 = 1 x 503 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1
Notice that 1 = HCF(503,1) .
