HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 847 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 486, 847 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 486, 847 is 1.
HCF(486, 847) = 1
HCF of 486, 847 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 847 is 1.
Highest Common Factor of 486,847 is 1
Step 1: Since 847 > 486, we apply the division lemma to 847 and 486, to get
847 = 486 x 1 + 361
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 361 and 486, to get
486 = 361 x 1 + 125
Step 3: We consider the new divisor 361 and the new remainder 125, and apply the division lemma to get
361 = 125 x 2 + 111
We consider the new divisor 125 and the new remainder 111,and apply the division lemma to get
125 = 111 x 1 + 14
We consider the new divisor 111 and the new remainder 14,and apply the division lemma to get
111 = 14 x 7 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 486 and 847 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(111,14) = HCF(125,111) = HCF(361,125) = HCF(486,361) = HCF(847,486) .
