HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 427, 284 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 427, 284 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, 427, 284 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, 427, 284 is 1.
HCF(487, 427, 284) = 1
HCF of 487, 427, 284 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, 427, 284 is 1.
Highest Common Factor of 487,427,284 is 1
Step 1: Since 487 > 427, we apply the division lemma to 487 and 427, to get
487 = 427 x 1 + 60
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 60 and 427, to get
427 = 60 x 7 + 7
Step 3: We consider the new divisor 60 and the new remainder 7, and apply the division lemma to get
60 = 7 x 8 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 427 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(60,7) = HCF(427,60) = HCF(487,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 284 > 1, we apply the division lemma to 284 and 1, to get
284 = 1 x 284 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 284 is 1
Notice that 1 = HCF(284,1) .
