HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 4903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 509, 4903 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 509, 4903 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 509, 4903 is 1.
HCF(509, 4903) = 1
HCF of 509, 4903 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 509, 4903 is 1.
Highest Common Factor of 509,4903 is 1
Step 1: Since 4903 > 509, we apply the division lemma to 4903 and 509, to get
4903 = 509 x 9 + 322
Step 2: Since the reminder 509 ≠ 0, we apply division lemma to 322 and 509, to get
509 = 322 x 1 + 187
Step 3: We consider the new divisor 322 and the new remainder 187, and apply the division lemma to get
322 = 187 x 1 + 135
We consider the new divisor 187 and the new remainder 135,and apply the division lemma to get
187 = 135 x 1 + 52
We consider the new divisor 135 and the new remainder 52,and apply the division lemma to get
135 = 52 x 2 + 31
We consider the new divisor 52 and the new remainder 31,and apply the division lemma to get
52 = 31 x 1 + 21
We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get
31 = 21 x 1 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 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 509 and 4903 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(52,31) = HCF(135,52) = HCF(187,135) = HCF(322,187) = HCF(509,322) = HCF(4903,509) .
