HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 5103, 9979 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 5103, 9979 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, 5103, 9979 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, 5103, 9979 is 1.
HCF(478, 5103, 9979) = 1
HCF of 478, 5103, 9979 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, 5103, 9979 is 1.
Highest Common Factor of 478,5103,9979 is 1
Step 1: Since 5103 > 478, we apply the division lemma to 5103 and 478, to get
5103 = 478 x 10 + 323
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 323 and 478, to get
478 = 323 x 1 + 155
Step 3: We consider the new divisor 323 and the new remainder 155, and apply the division lemma to get
323 = 155 x 2 + 13
We consider the new divisor 155 and the new remainder 13,and apply the division lemma to get
155 = 13 x 11 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 478 and 5103 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(155,13) = HCF(323,155) = HCF(478,323) = HCF(5103,478) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9979 > 1, we apply the division lemma to 9979 and 1, to get
9979 = 1 x 9979 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9979 is 1
Notice that 1 = HCF(9979,1) .
