HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 633, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 633, 805 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, 633, 805 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, 633, 805 is 1.
HCF(487, 633, 805) = 1
HCF of 487, 633, 805 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, 633, 805 is 1.
Highest Common Factor of 487,633,805 is 1
Step 1: Since 633 > 487, we apply the division lemma to 633 and 487, to get
633 = 487 x 1 + 146
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 146 and 487, to get
487 = 146 x 3 + 49
Step 3: We consider the new divisor 146 and the new remainder 49, and apply the division lemma to get
146 = 49 x 2 + 48
We consider the new divisor 49 and the new remainder 48,and apply the division lemma to get
49 = 48 x 1 + 1
We consider the new divisor 48 and the new remainder 1,and apply the division lemma to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 633 is 1
Notice that 1 = HCF(48,1) = HCF(49,48) = HCF(146,49) = HCF(487,146) = HCF(633,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get
805 = 1 x 805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1
Notice that 1 = HCF(805,1) .
