HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 828 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 828 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, 828 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, 828 is 1.
HCF(257, 828) = 1
HCF of 257, 828 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, 828 is 1.
Highest Common Factor of 257,828 is 1
Step 1: Since 828 > 257, we apply the division lemma to 828 and 257, to get
828 = 257 x 3 + 57
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 57 and 257, to get
257 = 57 x 4 + 29
Step 3: We consider the new divisor 57 and the new remainder 29, and apply the division lemma to get
57 = 29 x 1 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 257 and 828 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(257,57) = HCF(828,257) .
