HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 626, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 626, 499 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 478, 626, 499 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 478, 626, 499 is 1.
HCF(478, 626, 499) = 1
HCF of 478, 626, 499 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 478, 626, 499 is 1.
Highest Common Factor of 478,626,499 is 1
Step 1: Since 626 > 478, we apply the division lemma to 626 and 478, to get
626 = 478 x 1 + 148
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 148 and 478, to get
478 = 148 x 3 + 34
Step 3: We consider the new divisor 148 and the new remainder 34, and apply the division lemma to get
148 = 34 x 4 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 478 and 626 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(148,34) = HCF(478,148) = HCF(626,478) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 499 > 2, we apply the division lemma to 499 and 2, to get
499 = 2 x 249 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 499 is 1
Notice that 1 = HCF(2,1) = HCF(499,2) .
