HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 547, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 547, 193 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 998, 547, 193 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 998, 547, 193 is 1.
HCF(998, 547, 193) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 998, 547, 193 is 1.
Step 1: Since 998 > 547, we apply the division lemma to 998 and 547, to get
998 = 547 x 1 + 451
Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 451 and 547, to get
547 = 451 x 1 + 96
Step 3: We consider the new divisor 451 and the new remainder 96, and apply the division lemma to get
451 = 96 x 4 + 67
We consider the new divisor 96 and the new remainder 67,and apply the division lemma to get
96 = 67 x 1 + 29
We consider the new divisor 67 and the new remainder 29,and apply the division lemma to get
67 = 29 x 2 + 9
We consider the new divisor 29 and the new remainder 9,and apply the division lemma to get
29 = 9 x 3 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 998 and 547 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(29,9) = HCF(67,29) = HCF(96,67) = HCF(451,96) = HCF(547,451) = HCF(998,547) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 193 > 1, we apply the division lemma to 193 and 1, to get
193 = 1 x 193 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 193 is 1
Notice that 1 = HCF(193,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
