HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1423, 7478 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1423, 7478 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 1423, 7478 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 1423, 7478 is 1.
HCF(1423, 7478) = 1
HCF of 1423, 7478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1423, 7478 is 1.
Highest Common Factor of 1423,7478 is 1
Step 1: Since 7478 > 1423, we apply the division lemma to 7478 and 1423, to get
7478 = 1423 x 5 + 363
Step 2: Since the reminder 1423 ≠ 0, we apply division lemma to 363 and 1423, to get
1423 = 363 x 3 + 334
Step 3: We consider the new divisor 363 and the new remainder 334, and apply the division lemma to get
363 = 334 x 1 + 29
We consider the new divisor 334 and the new remainder 29,and apply the division lemma to get
334 = 29 x 11 + 15
We consider the new divisor 29 and the new remainder 15,and apply the division lemma to get
29 = 15 x 1 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1423 and 7478 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(334,29) = HCF(363,334) = HCF(1423,363) = HCF(7478,1423) .
