HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 2861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 2861 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 487, 2861 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 487, 2861 is 1.
HCF(487, 2861) = 1
HCF of 487, 2861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 2861 is 1.
Highest Common Factor of 487,2861 is 1
Step 1: Since 2861 > 487, we apply the division lemma to 2861 and 487, to get
2861 = 487 x 5 + 426
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 426 and 487, to get
487 = 426 x 1 + 61
Step 3: We consider the new divisor 426 and the new remainder 61, and apply the division lemma to get
426 = 61 x 6 + 60
We consider the new divisor 61 and the new remainder 60,and apply the division lemma to get
61 = 60 x 1 + 1
We consider the new divisor 60 and the new remainder 1,and apply the division lemma to get
60 = 1 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 2861 is 1
Notice that 1 = HCF(60,1) = HCF(61,60) = HCF(426,61) = HCF(487,426) = HCF(2861,487) .
