HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 871, 843 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 503, 871, 843 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 503, 871, 843 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 503, 871, 843 is 1.
HCF(503, 871, 843) = 1
HCF of 503, 871, 843 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 503, 871, 843 is 1.
Highest Common Factor of 503,871,843 is 1
Step 1: Since 871 > 503, we apply the division lemma to 871 and 503, to get
871 = 503 x 1 + 368
Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 368 and 503, to get
503 = 368 x 1 + 135
Step 3: We consider the new divisor 368 and the new remainder 135, and apply the division lemma to get
368 = 135 x 2 + 98
We consider the new divisor 135 and the new remainder 98,and apply the division lemma to get
135 = 98 x 1 + 37
We consider the new divisor 98 and the new remainder 37,and apply the division lemma to get
98 = 37 x 2 + 24
We consider the new divisor 37 and the new remainder 24,and apply the division lemma to get
37 = 24 x 1 + 13
We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get
24 = 13 x 1 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 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 503 and 871 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(37,24) = HCF(98,37) = HCF(135,98) = HCF(368,135) = HCF(503,368) = HCF(871,503) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 843 > 1, we apply the division lemma to 843 and 1, to get
843 = 1 x 843 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 843 is 1
Notice that 1 = HCF(843,1) .
