HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2469, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2469, 454 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 2469, 454 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 2469, 454 is 1.
HCF(2469, 454) = 1
HCF of 2469, 454 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2469, 454 is 1.
Highest Common Factor of 2469,454 is 1
Step 1: Since 2469 > 454, we apply the division lemma to 2469 and 454, to get
2469 = 454 x 5 + 199
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 199 and 454, to get
454 = 199 x 2 + 56
Step 3: We consider the new divisor 199 and the new remainder 56, and apply the division lemma to get
199 = 56 x 3 + 31
We consider the new divisor 56 and the new remainder 31,and apply the division lemma to get
56 = 31 x 1 + 25
We consider the new divisor 31 and the new remainder 25,and apply the division lemma to get
31 = 25 x 1 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2469 and 454 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(31,25) = HCF(56,31) = HCF(199,56) = HCF(454,199) = HCF(2469,454) .
