HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 1715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 1715 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, 1715 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, 1715 is 1.
HCF(487, 1715) = 1
HCF of 487, 1715 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, 1715 is 1.
Highest Common Factor of 487,1715 is 1
Step 1: Since 1715 > 487, we apply the division lemma to 1715 and 487, to get
1715 = 487 x 3 + 254
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 254 and 487, to get
487 = 254 x 1 + 233
Step 3: We consider the new divisor 254 and the new remainder 233, and apply the division lemma to get
254 = 233 x 1 + 21
We consider the new divisor 233 and the new remainder 21,and apply the division lemma to get
233 = 21 x 11 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 487 and 1715 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(233,21) = HCF(254,233) = HCF(487,254) = HCF(1715,487) .
