HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 2855, 4744 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 2855, 4744 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 257, 2855, 4744 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 257, 2855, 4744 is 1.
HCF(257, 2855, 4744) = 1
HCF of 257, 2855, 4744 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 257, 2855, 4744 is 1.
Highest Common Factor of 257,2855,4744 is 1
Step 1: Since 2855 > 257, we apply the division lemma to 2855 and 257, to get
2855 = 257 x 11 + 28
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 28 and 257, to get
257 = 28 x 9 + 5
Step 3: We consider the new divisor 28 and the new remainder 5, and apply the division lemma to get
28 = 5 x 5 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 257 and 2855 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(257,28) = HCF(2855,257) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4744 > 1, we apply the division lemma to 4744 and 1, to get
4744 = 1 x 4744 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4744 is 1
Notice that 1 = HCF(4744,1) .
