HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 514, 957, 304 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 514, 957, 304 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, 514, 957, 304 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, 514, 957, 304 is 1.
HCF(257, 514, 957, 304) = 1
HCF of 257, 514, 957, 304 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, 514, 957, 304 is 1.
Highest Common Factor of 257,514,957,304 is 1
Step 1: Since 514 > 257, we apply the division lemma to 514 and 257, to get
514 = 257 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 257, the HCF of 257 and 514 is 257
Notice that 257 = HCF(514,257) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 957 > 257, we apply the division lemma to 957 and 257, to get
957 = 257 x 3 + 186
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 186 and 257, to get
257 = 186 x 1 + 71
Step 3: We consider the new divisor 186 and the new remainder 71, and apply the division lemma to get
186 = 71 x 2 + 44
We consider the new divisor 71 and the new remainder 44,and apply the division lemma to get
71 = 44 x 1 + 27
We consider the new divisor 44 and the new remainder 27,and apply the division lemma to get
44 = 27 x 1 + 17
We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get
27 = 17 x 1 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 257 and 957 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(44,27) = HCF(71,44) = HCF(186,71) = HCF(257,186) = HCF(957,257) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 304 > 1, we apply the division lemma to 304 and 1, to get
304 = 1 x 304 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 304 is 1
Notice that 1 = HCF(304,1) .
