HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 436, 478 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 436, 478 is 2 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 404, 436, 478 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 404, 436, 478 is 2.
HCF(404, 436, 478) = 2
HCF of 404, 436, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 436, 478 is 2.
Highest Common Factor of 404,436,478 is 2
Step 1: Since 436 > 404, we apply the division lemma to 436 and 404, to get
436 = 404 x 1 + 32
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 32 and 404, to get
404 = 32 x 12 + 20
Step 3: We consider the new divisor 32 and the new remainder 20, and apply the division lemma to get
32 = 20 x 1 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 404 and 436 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(404,32) = HCF(436,404) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 4, we apply the division lemma to 478 and 4, to get
478 = 4 x 119 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 478 is 2
Notice that 2 = HCF(4,2) = HCF(478,4) .
