HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 287, 818 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 287, 818 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 287, 818 is 1.
HCF(287, 818) = 1
HCF of 287, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 287, 818 is 1.
Highest Common Factor of 287,818 is 1
Step 1: Since 818 > 287, we apply the division lemma to 818 and 287, to get
818 = 287 x 2 + 244
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 244 and 287, to get
287 = 244 x 1 + 43
Step 3: We consider the new divisor 244 and the new remainder 43, and apply the division lemma to get
244 = 43 x 5 + 29
We consider the new divisor 43 and the new remainder 29,and apply the division lemma to get
43 = 29 x 1 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 287 and 818 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(43,29) = HCF(244,43) = HCF(287,244) = HCF(818,287) .
