HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 760 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 760 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, 760 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, 760 is 1.
HCF(487, 760) = 1
HCF of 487, 760 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, 760 is 1.
Highest Common Factor of 487,760 is 1
Step 1: Since 760 > 487, we apply the division lemma to 760 and 487, to get
760 = 487 x 1 + 273
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 273 and 487, to get
487 = 273 x 1 + 214
Step 3: We consider the new divisor 273 and the new remainder 214, and apply the division lemma to get
273 = 214 x 1 + 59
We consider the new divisor 214 and the new remainder 59,and apply the division lemma to get
214 = 59 x 3 + 37
We consider the new divisor 59 and the new remainder 37,and apply the division lemma to get
59 = 37 x 1 + 22
We consider the new divisor 37 and the new remainder 22,and apply the division lemma to get
37 = 22 x 1 + 15
We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get
22 = 15 x 1 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 760 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(37,22) = HCF(59,37) = HCF(214,59) = HCF(273,214) = HCF(487,273) = HCF(760,487) .
