HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 446, 257 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 446, 257 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 446, 257 is 1.
HCF(446, 257) = 1
HCF of 446, 257 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 446, 257 is 1.
Highest Common Factor of 446,257 is 1
Step 1: Since 446 > 257, we apply the division lemma to 446 and 257, to get
446 = 257 x 1 + 189
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 189 and 257, to get
257 = 189 x 1 + 68
Step 3: We consider the new divisor 189 and the new remainder 68, and apply the division lemma to get
189 = 68 x 2 + 53
We consider the new divisor 68 and the new remainder 53,and apply the division lemma to get
68 = 53 x 1 + 15
We consider the new divisor 53 and the new remainder 15,and apply the division lemma to get
53 = 15 x 3 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 446 and 257 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(53,15) = HCF(68,53) = HCF(189,68) = HCF(257,189) = HCF(446,257) .
