HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 298 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 298 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 251, 298 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 251, 298 is 1.
HCF(251, 298) = 1
HCF of 251, 298 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 251, 298 is 1.
Highest Common Factor of 251,298 is 1
Step 1: Since 298 > 251, we apply the division lemma to 298 and 251, to get
298 = 251 x 1 + 47
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 47 and 251, to get
251 = 47 x 5 + 16
Step 3: We consider the new divisor 47 and the new remainder 16, and apply the division lemma to get
47 = 16 x 2 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 298 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(47,16) = HCF(251,47) = HCF(298,251) .
