HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 445, 496 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 445, 496 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, 445, 496 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, 445, 496 is 1.
HCF(487, 445, 496) = 1
HCF of 487, 445, 496 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, 445, 496 is 1.
Highest Common Factor of 487,445,496 is 1
Step 1: Since 487 > 445, we apply the division lemma to 487 and 445, to get
487 = 445 x 1 + 42
Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 42 and 445, to get
445 = 42 x 10 + 25
Step 3: We consider the new divisor 42 and the new remainder 25, and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 445 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(445,42) = HCF(487,445) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 1, we apply the division lemma to 496 and 1, to get
496 = 1 x 496 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 496 is 1
Notice that 1 = HCF(496,1) .
