HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 103, 990, 798, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 103, 990, 798, 197 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 103, 990, 798, 197 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 103, 990, 798, 197 is 1.
HCF(103, 990, 798, 197) = 1
HCF of 103, 990, 798, 197 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 103, 990, 798, 197 is 1.
Highest Common Factor of 103,990,798,197 is 1
Step 1: Since 990 > 103, we apply the division lemma to 990 and 103, to get
990 = 103 x 9 + 63
Step 2: Since the reminder 103 ≠ 0, we apply division lemma to 63 and 103, to get
103 = 63 x 1 + 40
Step 3: We consider the new divisor 63 and the new remainder 40, and apply the division lemma to get
63 = 40 x 1 + 23
We consider the new divisor 40 and the new remainder 23,and apply the division lemma to get
40 = 23 x 1 + 17
We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get
23 = 17 x 1 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 103 and 990 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(40,23) = HCF(63,40) = HCF(103,63) = HCF(990,103) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 798 > 1, we apply the division lemma to 798 and 1, to get
798 = 1 x 798 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 798 is 1
Notice that 1 = HCF(798,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get
197 = 1 x 197 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1
Notice that 1 = HCF(197,1) .
