HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 408 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 408 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, 408 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, 408 is 1.
HCF(251, 408) = 1
HCF of 251, 408 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, 408 is 1.
Highest Common Factor of 251,408 is 1
Step 1: Since 408 > 251, we apply the division lemma to 408 and 251, to get
408 = 251 x 1 + 157
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 157 and 251, to get
251 = 157 x 1 + 94
Step 3: We consider the new divisor 157 and the new remainder 94, and apply the division lemma to get
157 = 94 x 1 + 63
We consider the new divisor 94 and the new remainder 63,and apply the division lemma to get
94 = 63 x 1 + 31
We consider the new divisor 63 and the new remainder 31,and apply the division lemma to get
63 = 31 x 2 + 1
We consider the new divisor 31 and the new remainder 1,and apply the division lemma to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 408 is 1
Notice that 1 = HCF(31,1) = HCF(63,31) = HCF(94,63) = HCF(157,94) = HCF(251,157) = HCF(408,251) .
