HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 255, 6471 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 255, 6471 is 3 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 255, 6471 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 255, 6471 is 3.
HCF(255, 6471) = 3
HCF of 255, 6471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 255, 6471 is 3.
Highest Common Factor of 255,6471 is 3
Step 1: Since 6471 > 255, we apply the division lemma to 6471 and 255, to get
6471 = 255 x 25 + 96
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 96 and 255, to get
255 = 96 x 2 + 63
Step 3: We consider the new divisor 96 and the new remainder 63, and apply the division lemma to get
96 = 63 x 1 + 33
We consider the new divisor 63 and the new remainder 33,and apply the division lemma to get
63 = 33 x 1 + 30
We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get
33 = 30 x 1 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 255 and 6471 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(63,33) = HCF(96,63) = HCF(255,96) = HCF(6471,255) .
