HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 7390, 5518 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 803, 7390, 5518 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 803, 7390, 5518 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 803, 7390, 5518 is 1.
HCF(803, 7390, 5518) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 803, 7390, 5518 is 1.
Step 1: Since 7390 > 803, we apply the division lemma to 7390 and 803, to get
7390 = 803 x 9 + 163
Step 2: Since the reminder 803 ≠ 0, we apply division lemma to 163 and 803, to get
803 = 163 x 4 + 151
Step 3: We consider the new divisor 163 and the new remainder 151, and apply the division lemma to get
163 = 151 x 1 + 12
We consider the new divisor 151 and the new remainder 12,and apply the division lemma to get
151 = 12 x 12 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 803 and 7390 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(151,12) = HCF(163,151) = HCF(803,163) = HCF(7390,803) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5518 > 1, we apply the division lemma to 5518 and 1, to get
5518 = 1 x 5518 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 5518 is 1
Notice that 1 = HCF(5518,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
