HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 785, 867 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 503, 785, 867 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, 785, 867 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, 785, 867 is 1.
HCF(503, 785, 867) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 503, 785, 867 is 1.
Step 1: Since 785 > 503, we apply the division lemma to 785 and 503, to get
785 = 503 x 1 + 282
Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 282 and 503, to get
503 = 282 x 1 + 221
Step 3: We consider the new divisor 282 and the new remainder 221, and apply the division lemma to get
282 = 221 x 1 + 61
We consider the new divisor 221 and the new remainder 61,and apply the division lemma to get
221 = 61 x 3 + 38
We consider the new divisor 61 and the new remainder 38,and apply the division lemma to get
61 = 38 x 1 + 23
We consider the new divisor 38 and the new remainder 23,and apply the division lemma to get
38 = 23 x 1 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 503 and 785 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(38,23) = HCF(61,38) = HCF(221,61) = HCF(282,221) = HCF(503,282) = HCF(785,503) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 867 > 1, we apply the division lemma to 867 and 1, to get
867 = 1 x 867 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 867 is 1
Notice that 1 = HCF(867,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
