HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 5871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 5871 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 649, 5871 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 649, 5871 is 1.
HCF(649, 5871) = 1
HCF of 649, 5871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 5871 is 1.
Highest Common Factor of 649,5871 is 1
Step 1: Since 5871 > 649, we apply the division lemma to 5871 and 649, to get
5871 = 649 x 9 + 30
Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 30 and 649, to get
649 = 30 x 21 + 19
Step 3: We consider the new divisor 30 and the new remainder 19, and apply the division lemma to get
30 = 19 x 1 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 649 and 5871 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(649,30) = HCF(5871,649) .
