HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 257, 756 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, 756 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, 756 is 1.
HCF(257, 756) = 1
HCF of 257, 756 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, 756 is 1.
Highest Common Factor of 257,756 is 1
Step 1: Since 756 > 257, we apply the division lemma to 756 and 257, to get
756 = 257 x 2 + 242
Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 242 and 257, to get
257 = 242 x 1 + 15
Step 3: We consider the new divisor 242 and the new remainder 15, and apply the division lemma to get
242 = 15 x 16 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 756 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(242,15) = HCF(257,242) = HCF(756,257) .
