HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 503, 802 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, 802 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, 802 is 1.
HCF(503, 802) = 1
HCF of 503, 802 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, 802 is 1.
Highest Common Factor of 503,802 is 1
Step 1: Since 802 > 503, we apply the division lemma to 802 and 503, to get
802 = 503 x 1 + 299
Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 299 and 503, to get
503 = 299 x 1 + 204
Step 3: We consider the new divisor 299 and the new remainder 204, and apply the division lemma to get
299 = 204 x 1 + 95
We consider the new divisor 204 and the new remainder 95,and apply the division lemma to get
204 = 95 x 2 + 14
We consider the new divisor 95 and the new remainder 14,and apply the division lemma to get
95 = 14 x 6 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 802 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(95,14) = HCF(204,95) = HCF(299,204) = HCF(503,299) = HCF(802,503) .
