HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 25434 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 25434 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 451, 25434 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 451, 25434 is 1.
HCF(451, 25434) = 1
HCF of 451, 25434 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 25434 is 1.
Highest Common Factor of 451,25434 is 1
Step 1: Since 25434 > 451, we apply the division lemma to 25434 and 451, to get
25434 = 451 x 56 + 178
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 178 and 451, to get
451 = 178 x 2 + 95
Step 3: We consider the new divisor 178 and the new remainder 95, and apply the division lemma to get
178 = 95 x 1 + 83
We consider the new divisor 95 and the new remainder 83,and apply the division lemma to get
95 = 83 x 1 + 12
We consider the new divisor 83 and the new remainder 12,and apply the division lemma to get
83 = 12 x 6 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 451 and 25434 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(83,12) = HCF(95,83) = HCF(178,95) = HCF(451,178) = HCF(25434,451) .
